ISL43L220IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L220IR is a dual-channel, single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 1.65V to 3.6V and features a maximum on-resistance of 250 milliohms with a channel-to-channel matching of 5 milliohms. The device supports a switching time of 25 nanoseconds for both turn-on and turn-off periods. It is housed in an 8-TDFN package measuring 3x3 mm and functions within a temperature range of -40°C to 85°C.
