ISL43142IRZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43142IRZ-T is a quad analog switch manufactured by Renesas Electronics Corporation, featuring four independent SPST-NO/NC channels. It operates on a single supply of 2.7V to 12V or dual supplies of ±2.6V to 6V. Key electrical parameters include a maximum on-resistance of 65 ohms, channel-to-channel matching of 2 ohms, and turn-on/turn-off times of 80ns and 30ns respectively. The device exhibits low charge injection of 1pC and leakage current of 1nA, packaged in a 16-QFN (3x3) format.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates four precision SPST switches with selectable normally-open or normally-closed configurations within a single compact package.
• Delivers high signal integrity through low on-resistance and tight channel-to-channel matching for accurate data transmission.
• Minimizes signal distortion via ultra-low charge injection and high off-isolation characteristics suitable for precision applications.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement equipment
• Data acquisition systems requiring precise analog switching
• Communication interfaces for protocol conversion

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm that the component status remains End-of-Life as public records indicate discontinuation. Ensure compatibility with RoHS3 standards and check moisture sensitivity level requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple independent analog paths with flexible NO/NC configuration options. Consider the 16-QFN footprint constraints and thermal dissipation needs. Evaluate if the 65-ohm on-resistance meets the signal loss requirements of the target application bandwidth.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL43140-ISL43142 family of CMOS precision analog switches. It shares architectural similarities with the ISL43141 but adds configurable NC functionality. The series is designed for general-purpose analog signal switching in industrial and commercial environments.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between ISL43141 and ISL43142?

The ISL43141 features four SPST Normally-Open switches, while the ISL43142 provides four SPST switches that can be configured as either Normally-Open or Normally-Closed.

Does the 'T' suffix affect the electrical performance?

No, the 'T' suffix only denotes the tape-and-reel packaging format; the electrical specifications and pinout remain identical to the non-suffix version.
