ISL43L410IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43L410IR is a precision, bidirectional analog switch manufactured by Intersil. It features three single-pole double-throw (SPDT) switches within a single package. The device is designed to operate from a single supply voltage ranging from +2V to +12V or from dual supplies of ±2V to ±6V. Key electrical specifications include a maximum on-resistance of 50 Ohms and a typical on-time of 35 nanoseconds with an off-time of 22 nanoseconds. It supports signal voltages up to ±5V and operates within a temperature range of -40°C to +85°C in a 20-pin QFN package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IR' confirms the industrial temperature grade (-40°C to +85°C) and lead-free RoHS compliance status as documented in the official datasheet. Confirm the package type is QFN-20 and check for any specific ordering suffixes that may indicate tape-and-reel packaging versus cut tape options. Ensure the manufacturer designation matches Intersil or its successor entity Renesas for authenticity.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a design requires multiple low-voltage analog switches in a compact form factor. The ISL43L410IR is suitable for applications needing bidirectional signal flow and simultaneous channel inhibition. Consider the 50 Ohm on-resistance and ±5V signal limit against the system requirements. Compare against other members of the ISL43xxx family if different pin counts or resistance values are needed.
