ISL43L841IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L841IRZ-T is a dual-channel analog switch manufactured by Renesas Electronics under the Intersil brand. It features a single-pole four-throw (SP4T) topology with two independent circuits, providing a 4:1 multiplexing function. The device operates on a single supply voltage ranging from 1.65V to 4.5V. Key electrical specifications include a maximum on-resistance of 480 milliohms and a channel-to-channel matching of 120 milliohms. It supports data rates up to 100MHz with -100dB crosstalk at that frequency. The component is housed in a 16-TQFN package measuring 3x3 mm and functions within an ambient temperature range of -40°C to +85°C.
