UM4684H

Overview

The UM4684H is a low-voltage dual single-pole double-throw (SPDT) analog switch manufactured by Union Semiconductor, Inc. It features an ultra-low on-resistance of 0.5 ohms, enabling efficient signal routing in voltage-sensitive applications. The device supports bidirectional signal flow and operates within a specified temperature range suitable for industrial environments. Designed for compact integration, it utilizes a small form-factor package to minimize board space while maintaining high performance for audio, video, and communication signal switching tasks.

Feature Summary

Ultra-low on-resistance of 0.5 ohms for minimal signal attenuation
Dual SPDT configuration allowing independent channel control
Low-voltage operation capability for compatibility with modern logic levels

Applications

Audio and video signal routing systems
Communication equipment signal switching
Test and measurement instrument front ends

Part Context

The UM4684H belongs to the family of low-voltage analog switches designed for precision signal handling. It shares functional similarities with other dual SPDT devices like the LMS4684 and IDTAS4684, which also emphasize low on-resistance. This component serves as a specialized solution for applications requiring reliable switching with minimal impact on signal integrity in compact electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pinout compatibility and electrical specifications against alternatives such as the LMS4684 or IDTAS4684 before implementation.
