FN6028.1
Low-Voltage, Single Supply, SPST, High
Performance Analog Switches
Features
• Fully Specified at 3.3V, 5V, and 12V Supplies
• Available in SOT-23 Packaging
The Intersil ISL4311X are precision, high performance analog
switches that are fully specified for 3.3V, 5V, and 12V
operation, and feature improved leakage, Icc, and switching
time specifications.
• Single Supply Operation. . . . . . . . . . . . . . . . . +2.4V to +12V
• ON Resistance (R

Max). . . . . . . . . . . . . 20Ω (V+ = 5V)
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10Ω (V+ = 12V)
Designed to operate from a single +2.4V to +12V supply, the
low supply current (1µA Max over the temperature and
voltage ranges) and low leakage currents (1nA) make these
switches ideal for battery powered applications.
• R Flatness . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5Ω

• Charge Injection (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . 10pC
• Low Power Consumption (P Max). . . . . . . . . . . . . . . .<5µW

• Low Leakage Current (Max at 85oC) . 10nA (Off Leakage)
Low R

and fast switching speeds over a wide operating
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20nA (On Leakage)
supply range increase these devices usefulness in industrial
equipment, portable instruments, and as input signal
multiplexers for new generation, low supply voltage data
converters. Some of the smallest packages are available
alleviating board space limitations, and making Intersil’s
newest line of low-voltage switches an ideal solution.
• Fast Switching Action

• Minimum 2000V ESD Protection per Method 3015.7
• TTL, CMOS Compatible
The ISL4311X are single-pole/single-throw (SPST) switches,
with the ISL43110 being normally open (NO), and the
ISL43111 being normally closed (NC).
Applications
• Battery Powered, Handheld, and Portable Equipment
- Cellular/Mobile Phones, Pagers
Table 1 summarizes the performance of this family. For
similar performance ±5V supply versions, see the
ISL43112/13 data sheet.
- Laptops, Notebooks, Palmtops, PDAs

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
2. Signals on NO, NC, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
3. θ is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

Detailed Description
The ISL43110 and ISL43111 analog switches offer precise
switching capability from a single 2.4V to 12V supply with
low on-resistance and high speed operation. The devices
are especially well suited to portable battery powered
equipment thanks to the low operating supply voltage (2.4V),
low power consumption (5µW), low leakage currents (1nA
max), and the tiny SOT-23 packaging. High frequency
applications also benefit from the wide bandwidth, and the
very high off isolation.

increase, especially at low supply voltages.

Supply Sequencing And Overvoltage Protection
As with any CMOS device, proper power supply sequencing
is required to protect the device from excessive input
currents which might permanently damage the IC. All I/O
pins contain ESD protection diodes from the pin to V+ and to
GND (see Figure 6). To prevent forward biasing these
diodes, V+ must be applied before any input signals, and
input signal voltages must remain between V+ and GND. If
these conditions cannot be guaranteed, then one of the
following two protection methods should be employed.

FIGURE 6. OVERVOLTAGE PROTECTION
Logic inputs can easily be protected by adding a 1kΩ
resistor in series with the input (see Figure 6). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
produces an insignificant voltage drop during normal
operation.
Power-Supply Considerations
The ISL4311X construction is typical of most CMOS analog
switches, except that there are only two supply pins: V+ and
GND. Unlike switches with a 13V maximum supply voltage,
the ISL4311X 15V maximum supply voltage provides plenty
of room for the 10% tolerance of 12V supplies, as well as
room for overshoot and noise spikes.
Adding a series resistor to the switch input defeats the
purpose of using a low R
switch, so two small signal
ON
The minimum recommended supply voltage is 2.4V. It is
important to note that the input signal range, switching times,
and on-resistance degrade at lower supply voltages. Refer
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 6). These
additional diodes limit the analog signal from 1V below V+ to
1V above GND. The low leakage current performance is

Curves for details.
response is very consistent over a wide V+ range, and for
varying analog signal levels.
V+ and GND power the internal CMOS switches and set
their analog voltage limits. These supplies also power the
internal logic and level shifters. The level shifters convert the
input logic levels to switched V+ and GND signals to drive
the analog switch gate terminals.
An OFF switch acts like a capacitor and passes higher
frequencies with less attenuation, resulting in signal
feedthrough from a switch’s input to its output. Off Isolation
is the resistance to this feedthrough. Figure 16 details the
high Off Isolation provided by this family. At 10MHz, off
isolation is about 50dB in 50Ω systems, decreasing
approximately 20dB per decade as frequency increases.
Higher load impedances decrease Off Isolation due to the
voltage divider action of the switch OFF impedance and the
load impedance.
This family of switches cannot be operated with bipolar
supplies, because the input switching point becomes
negative in this configuration. For a ±5V single SPST switch,
see the ISL43112/13 data sheet.
Logic-Level Thresholds
Leakage Considerations
This switch family is TTL compatible (0.8V and 2.4V) over a
supply range of 3V to 11V, and the full temperature range
(see Figure 10). At 12V the low temperature V level is
about 2.5V. This is still below the TTL guaranteed high
output minimum level of 2.8V, but noise margin is reduced.
For best results with a 12V supply, use a logic family the
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and GND. One
of these diodes conducts if any analog signal exceeds V+ or
GND.
IH
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or GND and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the analog-
signal-path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given
switch can show leakage currents of the same or opposite
polarity. There is no connection between the analog-signal
paths and V+ or GND.

greater than 3V.
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails. Driving
the digital input signals from GND to V+ with a fast transition
time minimizes power dissipation.
High-Frequency Performance
In 50Ω systems, signal response is reasonably flat to
20MHz, with a -3dB bandwidth exceeding 200MHz (see
Figure 15). Figure 15 also illustrates that the frequency
