ISL43410

Low-Voltage, Single Supply, DPDT High

Performance Analog Switch

The Intersil ISL43410 is a precision, bidirectional, analog

switch configured as a double pole/double throw (DPDT)

switch. The ISL43410 is designed to operate from a single

+2V to +12V supply. It is equipped with an inhibit pin to

simultaneously open all signal paths.

ON-resistance is 115

Ω with a +5V supply, 45Ω with a +12V

supply, and 190

Ω with a +3V supply. Each switch can handle

rail-to-rail analog signals. The off-leakage current is only 3nA

at +25°C or 5nA at +85°C. All digital inputs have 0.8V to 2.4V

logic thresholds ensuring TTL/CMOS logic compatibility

when using a single +5V supply. 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 ISL43410 is a DPDT, which is perfect for use in 2-to-1

multiplexer applications.

Table 1 summarizes the performance of this switch.
