Analog Switches, Multiplexers, Demultiplexers datasheet and documents for ISL43231IRZ

ISL43231IRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43231IRZ is a precision, bidirectional analog switch configured as a triple single pole/double throw (SPDT) device. It operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. The ON resistance varies by supply voltage: maximum 50Ω at ±4.5V, 155Ω at +3V, and typical values of 39Ω at ±5V and 32Ω at +12V. Switching speeds include turn-on times ranging from 15ns to 70ns and turn-off times from 9ns to 37ns depending on the supply. The device features low charge injection (max 1pC at ±5V), guaranteed break-before-make timing, and TTL/CMOS logic compatibility.
