Overview
The DG455EY-T1-E3 is a high voltage quad SPST CMOS analog switch manufactured by Vishay Siliconix. It features four independently selectable switches with a typical on-resistance of 4 Ω and a typical flatness of 0.2 Ω. The device supports dual supplies up to ±15 V and a single supply of 12 V, handling analog signal ranges extending to the supply rails. Key electrical parameters include a maximum turn-on time of 118 ns and a maximum turn-off time of 97 ns at ±15 V. It operates within a temperature range of -40 °C to +125 °C and is housed in a 16-pin narrow SOIC package.
Feature Summary
- Four independently selectable high voltage SPST switches
- Low on-resistance with minimal flatness for low distortion audio switching
- TTL/CMOS compatible digital logic inputs without requiring a separate VL supply
- Fast switching speeds suitable for video applications
Applications
- Audio and video signal switching
- Precision automatic test equipment
- Relay replacement
- Sample and hold systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature rating. Confirm RoHS compliance status through official datasheets or component markings before integration into production designs.
Selection Notes
Select this component when high voltage handling and low distortion are required. Ensure the design accommodates the specified power dissipation limits and thermal derating requirements for the chosen operating environment.
Part Context
This part belongs to the DG454/DG455/DG456 series from Vishay Siliconix. The DG455 variant specifically provides normally open switches, distinguishing it from the DG454 (normally closed) and DG456 (mixed configuration). It serves as a pin-compatible alternative to older discrete solutions while eliminating the need for a level shift supply.

FAQ
Does the DG455 require a separate logic supply voltage?
No, the DG455 does not require a separate VL supply because its digital inputs are fully TTL/CMOS compatible.
What is the maximum analog signal range supported by this switch?
The device supports an analog signal range that extends to the supply voltage rails, typically up to ±15 V with dual supplies.
How does the DG455 differ logically from the DG454?
The DG455 consists of normally open switches, whereas the DG454 consists of normally closed switches; all other electrical characteristics remain identical.
