ISL43141WR5472

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141WR5472 is a CMOS precision quad analog switch manufactured by Renesas Electronics. It features four single-pole single-throw (SPST) normally open channels, operating from a +2V to +12V single supply or ±2V to ±6V dual supply. Key electrical parameters include a maximum on-state resistance of 65 Ohms, a maximum leakage current of 1nA, and a switching speed with a maximum turn-on time of 70 ns and turn-off time of 50 ns. The device supports a maximum switch DC current of 10 mA and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix WR5472 against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with required voltage levels and temperature ranges. Check for end-of-life status or obsolescence notices. Confirm moisture sensitivity level handling requirements during assembly. Validate that the component meets RoHS compliance standards for your region.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent SPST switches are needed in a compact form factor. Consider the 65 Ohm on-resistance limit for signal integrity requirements. Evaluate the ±2V to ±6V dual supply capability if bipolar signals are present. Compare switching speeds against system timing constraints. Assess board space limitations regarding the available package options.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43141 series consists of low-voltage, single and dual supply, high-performance quad SPST analog switches. The ISL43141 variant specifically provides four normally open switches, distinguishing it from the ISL43140 (normally closed) and ISL43142 (mixed NO/NC). These devices are designed for applications demanding low power, fast switching, and high accuracy in signal path management.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet indicates pin compatibility with DG411/DG412/DG413 devices. Verify electrical parameter overlaps before substitution. Ensure the replacement part supports the same supply voltage range and package dimensions.
