Data Sheet

FN6033.1

Low-Voltage, Single Supply, Dual SPST,

SPDT Analog Switches

Features

• Fully specified at 12V, 5V, and 3.3V supplies for 10%

tolerances

The Intersil ISL43120, ISL43121, ISL43122 and ISL43210

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 max), and fast switching speeds

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.

• Guaranteed break-before-make (ISL43122/ISL43210

only)

The ISL43120, ISL43121, ISL43122 are dual single-

pole/single-throw (SPST) devices. The ISL43120 has two

normally open (NO) switches; the ISL43121 has two normally

closed (NC) switches; the ISL43122 has one NO and one NC

switch and can be used as an SPDT. The ISL43210 is a

committed SPDT, which is perfect for use in 2-to-1 multiplexer

applications.

• Minimum 2000V ESD protection per method 3015.7

• TTL, CMOS compatible

• Available in SOT-23 packaging

Applications

• Battery powered, handheld, and portable equipment

- Cellular/mobile phones
