DG9421EDV-T1-GE3

Overview

The DG9421EDV-T1-GE3 is a monolithic single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a normally closed function and utilizes high-density BiCMOS technology to achieve low on-resistance, fast switching speed, and low power dissipation. The device operates on single supplies from +3 V to +16 V or dual supplies of ±3 V to ±8 V. Key electrical parameters include a typical on-resistance of 1.7 Ω at 12 V, a maximum on-resistance of 3.4 Ω across the full temperature range (-40 °C to +85 °C), and a -3 dB bandwidth of 161 MHz. It supports bi-directional rail-to-rail signal switching with a logic threshold compatible with 2.4 V control signals.

Feature Summary

Bi-directional rail-to-rail signal switching capability
Low on-resistance for excellent linearity and reduced distortion
Fast switching speed with high bandwidth
Logic input compatibility with simple interfacing

Applications

Automatic test equipment
Data acquisition systems
Audio and video signal routing
Relay replacement
Battery powered systems

Procurement Notes

Verify the component against official Vishay datasheet specifications before integration. Confirm that the package type matches the design requirements. Ensure operating conditions remain within the specified absolute maximum ratings to maintain reliability. Check for RoHS compliance status if required by project standards.

Selection Notes

Select this component when a normally closed SPST configuration is required. Consider the voltage range and on-resistance characteristics relative to the application's signal levels. Evaluate thermal performance based on the specified power dissipation limits in the TSOP-6 package.

Part Context

This part belongs to the DG9421E/DG9422E series of analog switches. The DG9421E variant specifically provides a normally closed function, distinguishing it from the DG9422E which offers a normally open configuration. Both share similar electrical characteristics and packaging options.
