UM3699A

Overview

The UM3699A is a dual double-pole double-throw (DPDT) ultra-low on-resistance analog switch manufactured by Union Semiconductor. It functions as a bidirectional signal routing component designed for low-voltage applications. The device integrates two independent DPDT switches within a single package, allowing for complex signal path configurations. Key electrical characteristics include an ultra-low Ron to minimize signal attenuation and distortion in the transmission path. It supports standard logic-level control inputs to select between the normally open and normally closed states of each switch channel.

Feature Summary

Dual DPDT topology enabling complex switching configurations
Ultra-low on-resistance for minimal signal loss
Bidirectional signal transmission capability
Low-voltage operation compatibility

Applications

Audio signal routing and switching
Video signal path selection
Telecommunications equipment
Test and measurement instrumentation

Part Context

The UM3699A belongs to the family of high-performance analog switches produced by Union Semiconductor. It is positioned as a solution for applications requiring precise signal routing with minimal insertion loss. Similar devices in this category often compete with offerings from major semiconductor manufacturers focusing on low RON and high isolation specifications for consumer and industrial electronics.

Replacement Considerations

Publicly confirmed substitute part numbers identified in distributor databases include NLAS3699 from ON Semiconductor and DG2015 or DG2017 from Vishay Siliconix. These alternatives share the dual DPDT architecture and low on-resistance profile. Verification of pinout compatibility and specific electrical parameter tolerances against the original design requirements is necessary before substitution.
