ISL43142IBZ-T

Analog Switches, Multiplexers, Demultiplexers Overview

The ISL43142IBZ-T is a high-speed analog switch manufactured by Renesas Electronics Corporation, housed in a 16-lead SOIC package. It integrates four independent single-pole single-throw (SPST) switches designed for signal routing applications. The device operates with a supply voltage range of 2.7V to 5.5V and supports bidirectional signal transmission. Key electrical parameters include an on-resistance of typically 8 ohms and a channel-to-channel matching of 0.05 ohm. The switch features low charge injection of 0.5 pC and a breakdown voltage of ±15V. Operating temperatures range from -40°C to +85°C, ensuring reliability in industrial environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'IBZ-T' corresponds to the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Confirm RoHS compliance status through the official datasheet or manufacturer documentation. Ensure the ordering code matches the required lead frame finish and moisture sensitivity level for your assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when four independent low-capacitance switches are required in a small footprint. Compare on-resistance flatness and break-before-make timing against alternative parts if signal fidelity is critical. Verify that the 5.5V maximum supply voltage aligns with your system's power rails and that the SOIC-16 package fits your PCB layout constraints.
