Low-Voltage, Single Supply, Dual SPST,
SPDT Analog Switches
Features
• Improved (lower R , faster switching), pin compatible

replacements for ISL84541–44
The Intersil ISL5120–ISL5123 devices are precision,
bidirectional, dual analog switches designed to operate from
a single +2.7V to +12V supply. Targeted applications include
battery powered equipment that benefit from the devices’ low
power consumption (5µW), low leakage currents (100pA

Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance.This family of parts may be used to “mux-
in” additional functionality while reducing ASIC design risk.
Some of the smallest packages are available, alleviating
board space limitations, and making Intersil’s newest line of
low-voltage switches an ideal solution.

The ISL5120/ISL5121/ISL5122 are dual single-pole/single-
throw (SPST) devices. The ISL5120 has two normally open
(NO) switches; the ISL5121 has two normally closed (NC)
switches; the ISL5122 has one NO and one NC switch and
can be used as an SPDT. The ISL5123 is a committed SPDT,
which is perfect for use in 2-to-1 multiplexer applications.
• Guaranteed break-before-make (ISL5122/ISL5123 only)
• Minimum 2000V ESD protection per method 3015.7
• TTL, CMOS compatible
• Available in SOT-23 packaging

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:
4. Signals on NC, NO, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward diode current to maximum current ratings.
5. θ is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

Power-Supply Considerations
Detailed Description
The ISL512X construction is typical of most CMOS analog
switches, except that they have only two supply pins:V+ and
GND. V+ and GND drive the internal CMOS switches and
set their analog voltage limits. Unlike switches with a 13V
maximum supply voltage, the ISL512X 15V maximum
supply voltage provides plenty of room for the 10% tolerance
of 12V supplies, as well as room for overshoot and noise
spikes.
The ISL5120–ISL5123 bidirectional, dual analog switches
offer precise switching capability from a single 2.7V to 12V
supply with low on-resistance (19Ω) and high speed
operation (t
= 28ns, t = 20ns). The devices are
ON
OFF
especially well suited to portable battery powered equipment
thanks to the low operating supply voltage (2.7V), low power
consumption (5µW), low leakage currents (100pA max), and
the tiny SOT-23 packaging. High frequency applications also
benefit from the wide bandwidth, and the very high off
isolation and crosstalk rejection.
The minimum recommended supply voltage is 2.7V. It is
important to note that the input signal range, switching times,
and on-resistance degrade at lower supply voltages. Refer
to the electrical specification tables and Typical Performance
curves for details.
Supply Sequencing And Overvoltage Protection
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 GND (see
Figure 8). 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.
V+ and GND 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.
This family of switches cannot be operated with bipolar
supplies, because the input switching point becomes
negative in this configuration.
Logic inputs can easily be protected by adding a 1kΩ
resistor in series with the input (see Figure 8). 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.
Logic-Level Thresholds
This switch family is TTL compatible (0.8V and 2.4V) over a
supply range of 3V to 11V (see Figure 15). At 12V the 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

ON
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.
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 8). These
additional diodes limit the analog signal from 1V below V+ to
1V above GND. The low leakage current performance is
unaffected by this approach, but the switch resistance may
increase, especially at low supply voltages.
High-Frequency Performance
In 50Ω systems, signal response is reasonably flat even past
300MHz (see Figure 16). Figure 16 also illustrates that the
frequency response is very consistent over a wide V+ range,
and for varying analog signal levels.
OPTIONAL PROTECTION
DIODE
V+
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, while Crosstalk
indicates the amount of feedthrough from one switch to
another. Figure 17 details the high Off Isolation and
Crosstalk rejection 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 and
Crosstalk rejection due to the voltage divider action of the
switch OFF impedance and the load impedance.

Leakage Considerations
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.
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.
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
