ISL43141IV-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141IV-T is a quad single-pole single-throw (SPST) analog switch manufactured by Renesas Electronics Corporation. It integrates four independent signal paths within a 16-pin TSSOP package, designed for low-voltage digital and analog signal routing. The device operates on a single supply voltage ranging from 2.7V to 12V or dual supplies of ±2.6V to ±6V. Key electrical specifications include a maximum on-resistance of 65 ohms, an on-resistance matching of 2 ohms between channels, and a charge injection of 1pC. Switching performance features a maximum turn-on time of 80ns and a turn-off time of 30ns. The component supports an operating temperature range of -40°C to +85°C and exhibits a leakage current of 1nA maximum.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm RoHS compliance status as per the latest manufacturer documentation. Check for End-of-Life notices or product change notifications that may affect long-term availability. Ensure the ordering part number matches the required package type and temperature grade.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required for low-voltage analog signal routing. Consider the 65-ohm on-resistance limit for signal loss calculations. Verify that the 80ns switching speed meets the system timing requirements. Ensure the 16-TSSOP footprint fits the PCB layout constraints compared to alternative packages like SOIC or QFN.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43141 belongs to the ISL4314x family of analog switches, which includes variants with different numbers of channels and contact types. This specific model provides four SPST normally-open switches. It complements other Renesas interface ICs such as multiplexers and level shifters in complete signal chain solutions. The device is part of Renesas's broader portfolio of mixed-signal integrated circuits for industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives within the ISL4314x series if different channel counts are needed. Verify functional equivalents from other manufacturers offering similar 4-channel SPST switches with comparable on-resistance and voltage ratings. Ensure any substitute maintains the same 16-TSSOP package dimensions for board compatibility.
