ISL43144IR-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43144IR-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 16-pin QFN package measuring 4x4 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 25 ohms, channel-to-channel matching of 500 milliohms, and a maximum charge injection of 5 picocoulombs. Switching times are specified at 65 nanoseconds for turn-on and 50 nanoseconds for turn-off.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix configuration against official documentation, as variations may exist. Confirm RoHS compliance status, as some sources indicate non-compliance for this part number. Check current manufacturing status, as discontinuation notices have been associated with similar Intersil/Renesas legacy parts. Ensure the supplier provides valid traceability for the Renesas brand.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated analog paths are required in a space-constrained design. Compare on-resistance and leakage current requirements against alternative packages like TSSOP if thermal performance differs. Verify that the 25-ohm on-resistance meets the application's signal loss budget. Ensure the 16-QFN footprint aligns with the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4314x family of high-speed analog switches from Renesas. The family includes variants with different on-resistance values and package options. The IR-T designation typically indicates a tape-and-reel packaging format for automated assembly. The product line bridges legacy Intersil technology with current Renesas portfolios.
