ISL43841IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43841IR-T is a dual 4-to-1 multiplexer analog switch manufactured by Renesas Electronics Corporation, housed in a 20-lead 4x4mm QFN package. It operates from single supplies of +2V to +12V or dual supplies of ±2V to ±6V. Key electrical parameters include an on-resistance (RON) of 50Ω maximum at ±4.5V and 155Ω maximum at +3V. The device features low charge injection of 1pC maximum at ±5V, off-leakage current of 2.5nA maximum, and switching times of 38ns (tON) and 19ns (tOFF) at +5V. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V to 2.4V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Features a latch bar pin to lock the last switch address for power-down retention.
Supports rail-to-rail analog signal handling across the full supply range.
Provides guaranteed break-before-make timing to prevent signal shorting.
Offers high off-isolation and crosstalk rejection suitable for high-frequency applications.

Telecom infrastructure and ADSL/VDSL modems
Medical ultrasound and MRI scanners
Audio and video signal routing systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the -T suffix indicates tape and reel packaging rather than tube. Confirm RoHS compliance status as standard IR versions may differ from IRZ variants. Check manufacturer documentation for moisture sensitivity level requirements during soldering. Ensure logic voltage levels match the specific supply voltage used in the design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when bidirectional switching with address latching is required. Verify that the on-resistance at the target supply voltage meets circuit loss requirements. Consider the 20-QFN package size for PCB layout constraints. Ensure input signals remain within the V+ and V- limits to avoid forward biasing internal ESD diodes.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the Intersil/Renesas ISL43841 family of precision analog switches. It is functionally identical to the ISL43841IR but differs in shipping configuration. The device was originally developed by Intersil Americas Inc. before acquisition by Renesas.
