ISL43142IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43142IR is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features four independent channels with normally open and normally closed configurations, housed in a 16-QFN package measuring 3x3 mm. The device supports a single supply voltage range of 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical specifications include a maximum on-resistance of 65 ohms, channel-to-channel matching of 2 ohms, and a maximum charge injection of 1pC. Switching times are specified at 80ns for turn-on and 30ns for turn-off, with a leakage current of 1nA maximum.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Provides four independent SPST switching channels with both normally open and normally closed contact options within a compact surface-mount package.
• Delivers precise signal routing capabilities with low on-resistance and high channel-to-channel matching accuracy for consistent performance across all channels.
• Operates effectively from a wide range of single or dual power supply voltages, accommodating various system power architectures.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm pin compatibility and thermal requirements against the 16-QFN datasheet specifications. Ensure that replacement strategies account for the discontinuation status and validate any substitute components against official cross-reference documentation provided by the manufacturer.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent analog switches with both NO and NC contacts are required in a small footprint. Consider the 65-ohm on-resistance and 80ns switching speed for applications where moderate signal integrity and speed are sufficient. Evaluate the 2.7V to 12V single supply range against system power constraints before finalizing the design.
