UM3156

Overview

The UM3156 is a low-voltage single-pole double-throw (SPDT) analog switch manufactured by Union Semiconductor International Limited. It utilizes advanced silicon gate CMOS technology to achieve very low propagation delay and on-resistance characteristics. The device integrates one circuit configured as a 2:1 switch with an on-resistance of 15 Ohms. It is housed in a compact SOT-363 surface-mount package, designed for applications requiring efficient signal routing in digital and consumer systems.

Feature Summary

Advanced CMOS fabrication using silicon gate technology
Low-voltage operation capability
Very low propagation delay performance
Low on-resistance specification

Applications

Industrial system signal routing
Consumer electronics signal switching
Digital system interface management

Procurement Notes

Verify the manufacturer designation matches Union Semiconductor International Limited or Union Semiconductor, Inc. Confirm the part number UM3156 corresponds to the SPDT analog switch description. Ensure the package type is SOT-363. Check datasheet specifications for voltage ranges and resistance values before integration.

Selection Notes

Select this component for applications requiring low-voltage analog signal switching with minimal delay. The 15 Ohm on-resistance suits precision signal paths. The SOT-363 package offers space efficiency for dense PCB layouts. Consider CMOS compatibility with surrounding logic circuits.

Part Context

This component belongs to the family of low-voltage analog switches produced by Union Semiconductor. It serves as a signal routing element in mixed-signal environments. The SPDT configuration allows connecting one common terminal to either of two output terminals based on control signals.
