ISL43L120IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L120IR-T is a dual single-pole/single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates from a single +1.65V to +3.6V supply and features ultra-low on-resistance of 0.16Ω at 3V and 0.26Ω at 1.8V. The device provides bidirectional signal switching with fast turn-on/turn-off times of 13ns at 3V and 30ns/25ns at 1.8V. It includes two normally open switches in an 8-lead 3x3mm TDFN package, offering low power consumption of 0.12µW and high off-isolation of 62dB at 100kHz.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the -T suffix indicates tape and reel packaging rather than standard tube delivery. Confirm RoHS compliance status as the base datasheet notes specific material sets for lead-free products. Ensure the ordering code matches the exact manufacturer part number to avoid compatibility issues with moisture sensitivity levels.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when board space is limited due to its compact 8-lead TDFN footprint. Choose this model for low-voltage single-supply designs requiring precise signal routing. Consider the 0.16Ω on-resistance for applications demanding high signal fidelity and low distortion across the operating voltage range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the ISL43L12X family, which also includes the ISL43L121 (dual NC) and ISL43L122 (NO/NC). All variants share identical electrical characteristics and pinouts but differ in switch configuration. The IR suffix denotes the 8-lead TDFN package format used in this specific part number.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include ISL43L120IU for MSOP packaging or ISL43L120IRZ for lead-free compliant versions. Verify that any substitute maintains the required 1.65V to 3.6V supply range and SPST NO configuration.
