ISL43L122IU

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L122IU is a dual-channel analog switch manufactured by Intersil, now part of Renesas Electronics. It features two SPST (Single Pole Single Throw) switches configured as NO/NC (Normally Open/Normally Closed) circuits within an 8-TDFN package. The device operates on a single supply voltage ranging from 1.65V to 3.6V. Key electrical parameters include 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. The component supports an operating temperature range of -40°C to +85°C and exhibits low charge injection of -125pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IU' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as some Intersil legacy parts may have varying environmental declarations. Check current product lifecycle status, as older Intersil models may be subject to discontinuation or obsolescence notices.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual isolated signal paths are required within a compact footprint. Ensure the system supply voltage remains within the 1.65V to 3.6V range to maintain specified on-resistance and leakage characteristics. Verify that the 250mΩ on-resistance meets the signal integrity requirements for the intended application bandwidth.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43L122 belongs to the ISL43L series of low-voltage analog switches. This family is characterized by ultra-low on-resistance and fast switching speeds, designed for battery-powered applications. The device integrates CMOS logic inputs compatible with standard digital interfaces while maintaining high analog signal fidelity.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations
