Low-Voltage, Single Supply, Dual SPST,
SPDT Analog Switches
The Intersil ISL5120, ISL5121, ISL5122, 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

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
• Pb-Free Available (RoHS Compliant)

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020C.
*Most surface mount devices are available on tape and reel;
add “-T” to suffix.

Supply Sequencing And Overvoltage Protection
Detailed Description
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.
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

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.
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

operation.
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
IH
Adding a series resistor to the switch input defeats the
level is about 2.5V. This is still below the TTL guaranteed
high output minimum level of 2.8V, but the noise margin is
reduced. For best results with a 12V supply, use a logic
purpose of using a low R
switch, so two small signal
ON
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.
family the provides a V
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.

DIODE
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.

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

Power-Supply Considerations
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.
Leakage Considerations
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
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.
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.
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.

lead flash and protrusions shall not exceed 0.25mm (0.010 inch) per
side.
5. The chamfer on the body is optional. If it is not present, a visual index
feature must be located within the crosshatched area.
6. “L” is the length of terminal for soldering to a substrate.
7. “N” is the number of terminal positions.
8. Terminal numbers are shown for reference only.
9. The lead width “B”, as measured 0.36mm (0.014 inch) or greater
above the seating plane, shall not exceed a maximum value of
0.61mm (0.024 inch).
10. Controlling dimension: MILLIMETER. Converted inch dimensions
are not necessarily exact.
