ISL43141IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141IR-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-VFQFN package with exposed pad, measuring 3x3 mm. The device supports single supply voltages from 2.7V to 12V and 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 low charge injection of 1pC. Switching times are specified at a maximum of 80ns for turn-on and 30ns for turn-off. The component operates within an ambient temperature range of -40°C to 85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration as distinct from standard tube packaging. Confirm RoHS compliance status through official Renesas documentation, as some variants in this series may not meet current environmental standards. Ensure the supplier provides valid traceability for the Renesas Electronics Corporation origin. Check for any end-of-life notifications or last-time buy notices associated with this specific part number before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required in a small form factor. The 65-ohm on-resistance suits general-purpose analog signal switching rather than precision low-impedance applications. Verify that the 2.7V minimum supply voltage aligns with the system's power architecture. Consider the 16-QFN package requirements for thermal dissipation and PCB layout constraints during the design phase.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43141 belongs to the ISL4314x family of CMOS analog switches from Renesas. This family offers various configurations including SPST and multiplexer options. The IR suffix typically denotes the industrial temperature grade and QFN package type. Related parts in the series may offer different pin counts or switching configurations while maintaining similar electrical characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must match the quad SPST topology and 16-pin QFN footprint. Verify equivalent on-resistance and supply voltage ranges. Cross-reference with other Renesas ISL4314x variants or competitive quad SPST switches ensuring pin compatibility and electrical parameter equivalence.
