MAX9140/MAX9141/
MAX9142/MAX9144
40ns, Low-Power, 3V/5V, Rail-to-Rail
Single-Supply Comparators
General Description
Features
● Fast, 40ns Propagation Delay (10mV Overdrive)
● Low Power
The MAX9140/MAX9141 are single and the MAX9142/
MAX9144 are dual/quad high-speed comparators optimized
for systems powered from a 3V or 5V supply. The MAX9141
features latch enable and device shutdown. These devices
combine high speed, low power, and rail-to-rail inputs.
Propagation delay is 40ns, while supply current is only
150μA per comparator.
• 150μA Supply Current Per Comparator (3V)
● Optimized for 3V and 5V Applications
● Rail-to-Rail Input Voltage Range
● Low, 500μV Offset Voltage
● Internal Hysteresis for Clean Switching
● Outputs Swing 300mV of Power Rails
● CMOS/TTL-Compatible Outputs
● Output Latch (MAX9141 Only)
The input common-mode range of the devices extends beyond
both power-supply rails. The outputs pull to within 0.3V of
either supply rail without external pullup circuitry, making these
devices ideal for interface with both CMOS and TTL logic. All
input and output pins can tolerate a continuous short-circuit
fault condition to either rail. Internal hysteresis ensures clean
output switching, even with slow-moving input signals.
● Shutdown Function (MAX9141 Only)
● Available in SC70 and SOT23 Packages
● AEC-Q100 Qualified (MAX9140AAXK/V+T Only)
The devices are higher-speed, lower-power, and lower-
cost upgrades to industry-standard comparators MAX941/
MAX942/MAX944.
The MAX9140 are offered in tiny 5-pin SC70 and SOT23
packages. The MAX9141 and MAX9142 are available in
8-pin SOT23 and SO packages, while the MAX9144 is
available in both 14-pin SO and TSSOP packages.
Applications
● Line Receivers
● Battery-Powered Systems
● Threshold Detectors/Discriminators
● 3V/5V Systems
● Zero-Crossing Detectors
● Sampling Circuits

Single-Supply Comparators
Detailed Description
The MAX9140/MAX9141/MAX9142/MAX9144 single-
supply comparators feature internal hysteresis, high
speed, and low power. Their outputs are pulled to within
300mV of either supply rail without external pullup or
pulldown circuitry. Rail-to-rail input voltage range and low-
voltage single-supply operation make these devices ideal
for portable equipment. The devices interface directly to
CMOS and TTL logic.

Most high-speed comparators oscillate in the linear region
because of noise or undesired parasitic feedback. This
tends to occur when the voltage on one input is at or
equal to the voltage on the other input. To counter the
parasitic effects and noise, the devices have an internal
hysteresis of 1.5mV.
V
OH
COMPARATOR
OUTPUT
V
OL
The hysteresis in a comparator creates two trip points:
one for the rising input voltage and one for the falling input
voltage (Figure 1). The difference between the trip points
is the hysteresis. The average of the trip points is the offset
voltage. When the comparator’s input voltages are equal,
the hysteresis effectively causes one comparator input
voltage to move quickly past the other, thus taking the
input out of the region where oscillation occurs. Standard
comparators require hysteresis to be added with external
resistors. The devices’ fixed internal hysteresis eliminates
these resistors. To increase hysteresis and noise margin
even more, add positive feedback with two resistors as a
voltage divider from the output to the noninverting input.
Figure 1. Input and Output Waveform, Noninverting Input
Varied
Input Stage Circuitry
The devices include internal protection circuitry that prevents
damage to the precision input stage from large differential
input voltages. This protection circuitry consists of two
back-toback diodes between IN+ and IN- as well as two
series 4.1kΩ resistors (Figure 3). The diodes limit the
differential voltage applied to the internal circuitry of the

the same, except the output would be inverted.

forward voltage drop of the diode (about 0.7V at +25°C).
The MAX9141 includes an internal latch that allows
storage of comparison results. The LE pin has a high input
impedance. If LE is high, the latch is transparent (i.e., the
comparator operates as though the latch is not present).
The comparator’s output state is latched when LEis pulled
low (Figure 2).
For a large differential input voltage (exceeding 2V ), this

protection circuitry increases the input bias current at IN+

3) Pay close attention to the decoupling capacitor’s bandwidth,
keeping leads short.
4) On the inputs and outputs, keep lead lengths short to avoid
unwanted parasitic feedback around the comparators.
1) Use a PCB with a good, unbroken, low-inductance
ground plane.
5) Solder the device directly to the PCB instead of using
a socket.
2) Place a decoupling capacitor (a 0.1μF ceramic capacitor
is a good choice) as close to V
as possible.
