ISL43140IR

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IR is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It features four independent channels with a maximum on-resistance of 65 ohms and a channel-to-channel matching of 2 ohms. 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 charge injection of 1pC, off-leakage current of 1nA, and crosstalk of -90dB at 100kHz. Switching times are specified as 80ns for turn-on and 30ns for turn-off. It operates within a temperature range of -40°C to 85°C and is housed in a 16-QFN (3x3) package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for available stock from third-party suppliers since direct manufacturing availability is limited. Ensure package compatibility with existing PCB footprints before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Consider the 65-ohm on-resistance limit when designing for low-voltage signal transmission. Evaluate the 2.7V minimum supply voltage against system power rails. Assess thermal performance within the -40°C to 85°C operating range. Compare channel isolation and crosstalk specifications against application noise requirements. Verify package dimensions for mechanical fit in constrained spaces.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43140IR belongs to the ISL4314x series of analog switches from Renesas. This family offers multi-channel switching solutions with consistent electrical characteristics across variants. The IR suffix indicates a specific tape-and-reel packaging option within the QFN form factor. Related parts in the series may offer different pin counts or resistance values while maintaining similar interface protocols.
