ISL43681IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43681IRZ-T is a precision, bidirectional analog switch configured as an 8-channel to 1-channel multiplexer. It operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. The device features low on-resistance (39Ω at ±5V), fast switching times (tON = 38ns, tOFF = 19ns at +5V), and low charge injection (1pC max). It includes inhibit pins to open all paths and a latch pin to lock the last address. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V to 2.4V. The component is housed in a 20-lead 4x4mm QFN package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Bidirectional signal routing with simultaneous path opening via inhibit pins
Address state retention using the latch bar control pin
TTL and CMOS logic compatibility across standard voltage rails
High-frequency performance with superior off-isolation and crosstalk rejection

Analog Switches, Multiplexers, Demultiplexers Applications

Medical imaging systems including MRI, CT, and PET scanners
Telecommunications infrastructure such as ADSL and VDSL modems
Audio and video signal routing networks
Test equipment like oscilloscopes and electrocardiographs

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the suffix 'T' indicates tape and reel packaging rather than tube. Confirm RoHS compliance status for the specific manufacturing lot. Check lead availability as Intersil products may have transitioned through various corporate acquisitions affecting stock levels.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring rail-to-rail analog signal handling within specified supply limits. Ensure the digital control logic meets the 0.8V to 2.4V threshold requirements for reliable switching. Consider thermal dissipation if operating near maximum current ratings in dense PCB layouts.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the ISL43681/ISL43741 family of low-voltage multiplexers originally manufactured by Intersil. Renesas Electronics Corporation now manages the product line following corporate mergers. The datasheet FN6053.3 provides the definitive technical specifications for design integration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43681IR serves as the tube-packaged equivalent. Verify functional compatibility with other 8:1 analog switches from the same manufacturer family before substitution.
