ISL43L120IRZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IRZ is a dual 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 limited to 25 nanoseconds for both turn-on and turn-off. Key electrical parameters include a charge injection of -125 picocoulombs, off-state leakage current of 3 nanamperes maximum, and crosstalk of -94 decibels at 100 kilohertz. It is housed in an 8-TDFN package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

This component has been officially discontinued and is no longer in production. Verification of availability should focus on surplus distributors or secondary markets rather than original manufacturer stock. Designers must confirm the authenticity of sourced units through rigorous testing due to the end-of-life status. Replacement strategies should prioritize compatible alternatives that meet the original electrical specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Selection requires verifying compatibility with the system's single-supply voltage range of 1.65V to 3.6V. The 250 milliohm on-resistance must be evaluated against the application's signal loss tolerance. Package constraints necessitate the use of 8-TDFN footprints. Designers should account for the -40°C to 85°C operating temperature range when defining environmental boundaries for the final assembly.
