ISL43140IV-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IV-T is a CMOS analog switch IC manufactured by Renesas Electronics, featuring four independent single-pole single-throw (SPST) channels. It operates on a single supply voltage ranging from 2V to 12V or dual supplies of ±1V to ±6V. The device offers a maximum on-resistance of 65 Ohms and supports a continuous DC switch current of 10 mA. Key timing parameters include a maximum turn-on time of 70 ns and a maximum turn-off time of 50 ns. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging versus the standard tube configuration found in other variants like ISL43140IVZ. Confirm end-of-life status as the base model ISL43140IVZ is listed as obsolete. Ensure RoHS compliance documentation matches the specific manufacturing lot and revision level required for your assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four isolated signal paths are required within a limited board area. Compare the 65 Ohm on-resistance against application requirements for signal integrity. Verify that the 10 mA switch current capability meets the load demands. Consider the TSSOP-16 footprint constraints during PCB layout planning.
