ISL43140IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IR-T is a quad single-pole single-throw normally open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent SPST switches within a compact 16-VFQFN package featuring an exposed thermal pad. The device supports single supply voltages ranging from 2.7V to 12V and dual supplies of ±2.6V to ±6V. Key electrical characteristics include a maximum on-resistance of 65 ohms, channel-to-channel matching of 2 ohms, and low charge injection of 1pC. Switching times are specified at a maximum of 80ns for turn-on and 30ns for turn-off. The component operates across an extended temperature range of -40°C to +85°C.
