ISL43L120IUZ

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IUZ 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 25ns for both turn-on and turn-off. Key electrical parameters include a charge injection of -125pC, off-state leakage current of 3nA, and crosstalk of -94dB at 100kHz. It is housed in an 8-MSOP package and functions within a temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPST configuration with normally-open logic for independent signal path control
• Low on-resistance of 250 milliohms ensures minimal signal attenuation
• High channel-to-channel matching supports precision differential applications

Analog Switches, Multiplexers, Demultiplexers Applications

• Portable battery-powered instrumentation requiring low voltage operation
• Signal routing in data acquisition systems
• Audio and video signal switching circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the base part may not meet current standards. Validate package integrity upon receipt to ensure suitability for surface mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated switches are required under 3.6V supplies. Compare against ISL43L121 for normally-closed variants or ISL43L120IR for TDFN packaging options. Ensure input signals remain within the specified supply voltage limits to prevent latch-up conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43L12x family of low-voltage analog switches. It shares core specifications with the ISL43L120IR, differing primarily in the MSOP package variant. The series is designed for high-density PCB layouts in consumer electronics and industrial control modules.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include ISL43L120IR for identical electrical performance in a different package. Verify pin compatibility before substitution.
