ISL43L120IU

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IU is a dual single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation, formerly Intersil. It operates on a single supply voltage ranging from 1.65V to 3.6V. The device features a maximum on-resistance of 250 milliohms and 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, leakage current of 3nA, and crosstalk of -94dB at 100kHz. It is housed in an 8-MSOP package and supports an operating temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Check for RoHS compliance status as indicated in official documentation. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions meet moisture sensitivity level requirements to prevent damage before soldering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent analog switches are required within a compact surface-mount footprint. Consider the 1.65V minimum supply voltage for compatibility with modern low-voltage systems. Evaluate the 250mΩ on-resistance against signal loss requirements in the specific application path.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43L120IU belongs to the ISL43L12x series of low-voltage analog switches. It shares functional similarities with the ISL43L121 and ISL43L122, differing primarily in contact configuration. The part was originally developed by Intersil Corporation before its acquisition by Renesas Electronics.
