ISL43L120IUZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IUZ-T is a dual single-pole/single-throw (SPST) analog switch from the Intersil ISL43L12X family, manufactured by Renesas Electronics. It operates on a single supply voltage ranging from +1.65V to +3.6V and features two normally open switches. The device provides an ultra-low ON-resistance of 0.16Ω at 3V and 0.26Ω at 1.8V, with channel matching of 0.005Ω. It supports fast switching speeds with turn-on/turn-off times as low as 13ns at 3V. Packaged in an 8-lead MSOP, it is designed for low power consumption and high isolation in portable applications.
