1.8V, Nanopower,
PUSH-PULL OUTPUT COMPARATOR
DESCRIPTION
FEATURES
The TLV349x family of push-pull output comparators fea-
tures a fast 6µs response time and < 1.2µA (max) nanopower
capability, allowing operation from 1.8V – 5.5V. Input com-
mon-mode range beyond supply rails make the TLV349x an
ideal choice for low-voltage applications.
● VERY LOW SUPPLY CURRENT: 0.8µA (typ)
● INPUT COMMON-MODE RANGE 200mV
BEYOND SUPPLY RAILS
● SUPPLY VOLTAGE: +1.8V to +5.5V
● HIGH SPEED: 6µs
Micro-sized packages provide options for portable and space-
restricted applications. The single (TLV3491) is available
in SOT23-5 and SO-8. The dual (TLV3492) comes in
SOT23-8 and SO-8. The quad (TLV3494) is available in
TSSOP-14 and SO-14.
● PUSH-PULL CMOS OUTPUT STAGE
● SMALL PACKAGES:
SOT23-5 (Single)
SOT23-8 (Dual)
The TLV349x is excellent for power-sensitive, low-voltage
(2-cell) applications.

ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
NOTE: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may de-
grade device reliability. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those specified is
not implied. (2) Input terminals are diode-clamped to the power-supply rails.
Input signals that can swing more than 0.5V beyond the supply rails should
be current limited to 10mA or less. (3) Short-circuit to ground, one amplifier

SETTING REFERENCE VOLTAGE
APPLICATIONS INFORMATION
It is important to use a stable reference when setting the
transition point for the TLV349x. The REF1004 provides a
1.25V reference voltage with low drift and only 8µA of
quiescent current.
The TLV349x family of comparators features rail-to-rail input
and output on supply voltages as low as 1.8V. The push-pull
output stage is optimal for reduced power budget applica-
tions and features no shoot-through current. Low supply
voltages, common-mode input range beyond supply rails,
and a typical supply current of 0.8µA make the TLV349x
family an excellent candidate for battery-powered applica-
tions with single-cell operation.
EXTERNAL HYSTERESIS
Comparator inputs have no noise immunity within the range
of specified offset voltage (±15mV). For noisy input signals,
the comparator output may display multiple switching as
input signals move through the switching threshold. The
typical comparator threshold of the TLV349x is ±15mV. To
prevent multiple switching within the comparator threshold of
the TLV349x, external hysteresis may be added by connect-
ing a small amount of feedback to the positive input. Figure
2 shows a typical topology used to introduce hysteresis,
described by the equation:
BOARD LAYOUT
Figure 1 shows the typical connections for the TLV349x. To
minimize supply noise, power supplies should be capaci-
tively decoupled by a 0.01µF ceramic capacitor in parallel
with a 10µF electrolytic capacitor. Comparators are very
sensitive to input noise. Proper grounding (use of ground
plane) will help maintain specified performance of the TLV349x
family.

a simple resistor divider. These resistor values should be
relatively high to reduce the current consumption of the
circuit. The positive input is an RC circuit that provides a
power-up delay. When power is applied, the output of the
comparator is low, holding the processor in the reset condi-
tion. Only after allowing time for the supply voltage to
stabilize does the positive input of the comparator become
higher than the negative input, resulting in a high output state
and releasing the processor for operation. The stabilization
time required for the supply voltage is adjustable by the
selection of the RC component values. Use of a lower-valued
resistor in this portion of the circuit will not increase current
consumption because no current flows through the RC circuit
after the supply has stabilized. The reset delay time needed
depends on the power-up characteristics of the system
power supply. R1 and C1 are selected to allow enough time
for the power supply to stabilize. D1 provides rapid reset if
power is lost. In this example, the R1 • C1 time constant is
10ms.
APPLICATIONS
RELAXATION OSCILLATOR
The TLV349x can be configured as a relaxation oscillator to
provide a simple and inexpensive clock output (see Figure
3.) The capacitor is charged at a rate of 0.69RC. It also
discharges at a rate of 0.69RC. Therefore, the period is
1.38RC. R1 may be a different value than R2.

The reset circuit shown in Figure 4 provides a time delayed
release of reset to the MSP430 microcontroller. Operation of
the circuit is based on a stabilization time constant of the
supply voltage, rather than on a predetermined voltage
value. The negative input is a reference voltage created by

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
