ISL43143IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43143IR-T is a quad single-pole single-throw (SPST) normally-open analog switch manufactured by Renesas Electronics Corporation. It integrates four independent channels within a compact 16-pin TSSOP package, designed for signal routing in electronic systems. The device operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical characteristics include a maximum on-resistance of 65 ohms and a channel-to-channel matching of 2 ohms. Switching performance features a maximum turn-on time of 80ns and a turn-off time of 30ns. The component supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status as older Intersil-branded variants may differ. Ensure the supplier provides valid traceability documentation for the Renesas Electronics Corporation origin. Cross-reference the full part number against current manufacturer databases to confirm active production status before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad-channel configuration is required for space-constrained designs. The 65-ohm on-resistance suits applications with moderate load requirements. Consider the 80ns switching speed for general-purpose signal routing rather than high-frequency RF applications. Verify that the 16-pin TSSOP footprint aligns with the target PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4314x family of analog switches, which includes variants like the ISL43141 and ISL43144. These devices share similar functional architectures but differ in on-resistance values and package options. The ISL43143 specifically offers a balance between resistance and switching speed within the quad-channel segment of the portfolio.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The ISL43141IRZ is listed as a discontinued alternative with similar specifications. Verify pin compatibility and on-resistance differences when substituting. Check for updated RoHS compliance if replacing older stock.
