ISL43140IV

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IV is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It operates on a single supply voltage ranging from 2 V to 12 V or dual supplies of ±2 V to ±6 V. The device features a maximum on-resistance of 65 Ohms, with a typical switching time of 70 ns for turn-on and 50 ns for turn-off. It supports a continuous DC current of 10 mA per channel and draws a maximum supply current of 1 uA. The component is housed in a 16-TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix IV against official Renesas documentation to confirm the exact package variant and industrial temperature rating. Confirm RoHS compliance status through the manufacturer's latest datasheet as regulatory requirements may evolve over time.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Ensure the application voltage stays within the 2 V to 12 V single supply limit. Consider the 65 Ohm on-resistance impact on signal integrity for high-impedance sources.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the ISL4314x series of CMOS analog switches. It shares functional similarities with the ISL43141 and ISL43142 but differs in specific electrical characteristics such as on-resistance and charge injection. The series is designed for general-purpose signal switching tasks.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the ISL43141IVZ and ISL43142IVZ. Verify pin compatibility and electrical parameter alignment before substitution.
