ISL43140IB-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43140IB-T is a CMOS precision quad analog switch manufactured by Renesas Electronics Corporation. It features four independent single-pole single-throw (SPST) channels within a 16-SOIC package. The device operates from a single +2V to +12V supply or dual ±2V to ±6V supplies. Key electrical parameters include an on-state resistance of 65 Ohms and a channel-to-channel matching of 2 Ohms, ensuring high signal integrity.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IB-T' against official Renesas documentation to confirm tape-and-reel packaging and temperature range specifications. Ensure compatibility with required voltage rails before integration. Cross-reference part numbers carefully as Intersil legacy parts may have updated designations under Renesas.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise channel matching and low on-resistance are critical for signal integrity. Consider the 16-SOIC package constraints for PCB layout. Evaluate power supply requirements against the specified operating voltage ranges to ensure proper functionality across the industrial temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Intersil ISL4314x series of precision analog switches, now part of the Renesas portfolio. It is designed for applications demanding high accuracy and low distortion. The series includes variants with different resistance values, with the ISL43140 offering specific 65 Ohm characteristics suitable for general precision switching tasks.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Consult official cross-reference lists for direct substitutes such as the ISL43140IB without the tape suffix if reel packaging is not required. Verify pinout and electrical specifications match exactly before replacing to maintain system performance.
