ISL43L220IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L220IR-T is a dual single-pole/double-throw (SPDT) analog switch manufactured by Renesas Electronics Corporation. It operates from a single +1.1V to +4.5V supply and features ultra-low on-resistance, ranging from 0.22Ω at 4.3V to 3Ω at 1.1V. The device provides fast switching speeds with turn-on times as low as 5ns and turn-off times down to 8ns depending on the supply voltage. Packaged in a 10-lead 3x3mm thin DFN, it supports bidirectional signal paths and includes normally open and normally closed switches for multiplexing applications.
