DG9425EDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG9425EDQ-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features four normally closed switches that respond to opposite logic levels compared to the DG9424E variant. The device operates on single supplies from 3 V to 16 V or dual supplies from ±3 V to ±8 V. Key electrical parameters include a typical on-resistance of 1.6 Ω, maximum turn-on time of 51 ns at room temperature, and charge injection of 38 pC. It supports bidirectional rail-to-rail signal switching with low leakage current and is housed in a 16-lead TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic quad SPST configuration with normally closed contacts
• Low and flat on-resistance over full input signal voltage range for excellent linearity
• Fast switching speed with low power dissipation
• Low voltage logic control threshold compatible with 3 V logic

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems
• Programmable gain control applications
• Audio and video signal routing
• Reed relay replacement
• Automatic test equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'T1-GE3' against the manufacturer's official documentation to confirm the tape and reel packaging quantity and RoHS compliance status. Ensure the component matches the 16-lead TSSOP physical dimensions and pinout configuration required for the target printed circuit board layout before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed analog switch configuration is required, as it responds to opposite logic levels compared to the DG9424E. Verify that the supply voltage range of 3 V to 16 V aligns with the system design. Consider the 1.6 Ω typical on-resistance and 38 pC charge injection specifications for signal integrity requirements in precision data acquisition or audio applications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG9424E/DG9425E/DG9426E family of quad SPST analog switches. While functionally similar regarding electrical performance, the DG9425E is distinguished by its normally closed switch state and inverted logic control response relative to the DG9424E. The family utilizes BiCMOS wafer fabrication technology to enable operation on both single and dual power supplies.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG9424EDQ-T1-GE3 serves as a direct functional substitute if the application requires normally open switches instead of normally closed ones, assuming identical logic level compatibility. The DG9426EDQ-T1-GE3 offers mixed normally open/closed configurations but lacks the uniform quad normally closed topology.
