ISL43L120IU-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IU-T is a dual-channel, single-pole single-throw (SPST) normally open analog switch manufactured by Renesas Electronics. It operates on a single supply voltage ranging from 1.65V to 3.6V. The device features a maximum on-resistance of 250 milliohms with a channel-to-channel matching of 5 milliohms. Switching times are specified at 25ns for both turn-on and turn-off. Key electrical parameters include a charge injection of -125pC, off-state leakage current of 3nA maximum, and a crosstalk rejection of -94dB at 100kHz. It is housed in an 8-TDFN (3x3) package and supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IU' against the manufacturer's official documentation to confirm pinout compatibility and tape-and-reel specifications. Confirm RoHS compliance status as some variants may differ. Ensure the component source is authorized to avoid counterfeit risks given the discontinued status of similar Intersil parts.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low on-resistance and high bandwidth are required within a low-voltage single-supply environment. Compare the 250mOhm Ron against higher resistance alternatives if signal integrity is critical. Verify that the 8-TDFN package dimensions fit the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L120 family of low-power analog switches. It shares functional similarities with the ISL43L121 and ISL43L122 but differs in specific electrical characteristics and packaging options. The series is designed for applications requiring small form factors and efficient power management.
