ISL43L122IU-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L122IU-T is a dual-channel analog switch manufactured by Renesas Electronics Corporation, formerly Intersil. It features two independent SPST switches configured as one normally open and one normally closed channel within an 8-MSOP package. The device operates on a single supply voltage ranging from 1.65V to 3.6V. Key electrical specifications include a maximum on-resistance of 250 milliohms with a channel-to-channel matching of 5 milliohms. Switching times are limited to 25ns for both turn-on and turn-off. Leakage current is specified at a maximum of 3nA, while charge injection measures -125pC. The component supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual-channel architecture providing one normally open and one normally closed SPST circuit per package
• Low on-resistance performance with tight channel-to-channel matching for signal integrity
• Ultra-low leakage current and minimal charge injection suitable for precision applications

Analog Switches, Multiplexers, Demultiplexers Applications

• Portable instrumentation requiring low power consumption
• Battery-powered measurement systems
• Audio signal routing in consumer electronics

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration against official datasheets. Confirm RoHS compliance status as some variants may not meet current environmental standards. Check for obsolescence notices or lifecycle changes from Renesas Electronics before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual-channel switching with mixed NO/NC functionality is required in a compact surface-mount package. Ensure the single-supply voltage range aligns with system rails. Consider the 250mΩ on-resistance limit for signal attenuation requirements in the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L12x series of low-voltage analog switches. It shares core electrical characteristics with the ISL43L120 and ISL43L121 but differs in switch configuration. The 'IU' designation specifies the 8-MSOP package type, while 'T' typically denotes reel packaging for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the ISL43L120IU-T and ISL43L121IU-T if switch configurations match requirements. Verify pinout compatibility and package dimensions when replacing with other MSOP-8 analog switches from different manufacturers.
