DG9424EDQ-T1-GE3

Overview

The DG9424EDQ-T1-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on single supplies from 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device features a typical on-resistance of 1.6 Ω at ±5 V and supports bidirectional rail-to-rail signal switching. It utilizes BiCMOS technology for low power dissipation, fast switching speeds, and low charge injection. The component is housed in a 16-lead TSSOP package and functions within an operating temperature range of -40 °C to +85 °C.

Feature Summary

• BiCMOS wafer fabrication technology enables operation on both single and dual supply voltages with low power dissipation.
• Low and flat on-resistance across the full input signal voltage range ensures excellent linearity and reduced signal distortion.
• Proprietary design minimizes charge injection to reduce switching transients during operation.
• Logic control threshold compatible with 3 V logic levels for simple interfacing.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'T1' corresponds to the tape and reel packaging format containing 3000 units per standard pack quantity. Confirm that the 'GE3' designation aligns with current environmental compliance requirements before finalizing procurement specifications.

Selection Notes

Select this component when a quad SPST configuration with low on-resistance is required for data acquisition or programmable gain control. Ensure the application voltage falls within the 3 V to 16 V single supply or ±3 V to ±8 V dual supply limits. Verify that the TSSOP-16 package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the DG9424E/DG9425E/DG9426E family of quad SPST switches. The DG9424E specifically responds to logic level 0 to turn on, distinguishing it from the DG9425E which uses logic level 1. Both share identical electrical characteristics and pinouts but differ only in their logic sense control.

Replacement Considerations

The DG9425EDQ-T1-GE3 serves as a functional substitute with inverted logic control. The DG9426EDQ-T1-GE3 offers mixed normally open and normally closed configurations. Cross-reference the specific logic requirements and break-before-make timing needs when evaluating these alternatives.

FAQ

How does the DG9424E differ from the DG9425E?

The DG9424E and DG9425E differ only in their logic response; the DG9424E turns on with a logic level 0, while the DG9425E turns on with a logic level 1.

What is the maximum analog signal range for single supply operation?

For single supply operation, the analog signal range extends from the negative supply rail (V-) to the positive supply rail (V+), supporting up to 16 V.

Does this device support break-before-make switching?

No, break-before-make switching is a feature specific to the DG9426E variant. The DG9424E does not include this functionality.
