ISL43141IB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43141IB-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 SOIC-Narrow package. The device supports single supply voltages from 2V to 12V and dual supplies of ±2V to ±6V. Key electrical specifications include a maximum on-resistance of 65 ohms, channel-to-channel matching of 2 ohms, and a leakage current of 1nA maximum. Switching times are specified at 70ns for turn-on and 50ns for turn-off. The component operates within an industrial temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB-T' against official Renesas documentation to confirm tape-and-reel packaging and industrial temperature grade. Confirm end-of-life status as similar variants like ISL43141IBZ are listed as obsolete. Request current manufacturer datasheets to validate pinout compatibility and replacement availability before procurement planning.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance and standard switching speeds. Ensure the operating voltage range aligns with the 2V to 12V single supply limit. Consider package constraints as it utilizes a 16-pin narrow SOIC footprint. Verify that the 65-ohm on-resistance meets the signal loss requirements of the application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The ISL43141 belongs to the ISL4314x series of analog switches from Renesas, which also includes variants like ISL43141IRZ and ISL43141IVZ. These parts share similar electrical characteristics but differ in packaging, such as QFN or TSSOP options. The series is designed for general-purpose analog signal switching in industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public sources list ADG1212YCPZ-500RL7 as a similar substitute. Verify functional equivalence regarding channel count, on-resistance, and package dimensions. Check if alternative packages like ISL43141IVZ are available if the SOIC form factor is not strictly mandatory.
