DG456EY-T1-E3

Overview

The DG456EY-T1-E3 is a high voltage quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It features four independently selectable switches with two normally closed and two normally open configurations. The device operates with dual supplies up to ±15 V or a single supply of 12 V, supporting a maximum supply rating of 44 V. Key electrical parameters include a typical on-resistance of 4 Ω, a maximum turn-on time of 118 ns, and a maximum turn-off time of 97 ns at ±15 V. It provides an analog signal range extending to the supply rails and requires no separate logic supply voltage.

Feature Summary

• Four independent SPST switches with mixed normally open and normally closed configurations
• High voltage capability with analog signal range extending to supply rails
• Low on-resistance with high flatness for low distortion audio switching
• TTL/CMOS compatible digital inputs without requiring a separate logic supply

Applications

• Audio and video signal switching
• Precision automatic test equipment
• Relay replacement
• Sample and hold systems

Procurement Notes

Verify the specific package type against design requirements, as this part number denotes the narrow SOIC-16 variant. Confirm that the operating temperature range of -40 °C to +125 °C aligns with system constraints. Ensure power dissipation limits are respected within the thermal environment. Cross-reference the datasheet revision date to confirm current specifications before finalizing procurement.

Selection Notes

Select this component when high voltage handling and rail-to-rail signal transmission are required. The DG456 offers a mix of normally open and normally closed channels, distinguishing it from the DG454 and DG455 variants. Verify that the 100 mA continuous current rating meets load requirements. Consider the pin compatibility with the DG411/DG412/DG413 series if upgrading existing designs, noting the elimination of the VL supply requirement.

Part Context

This component belongs to the DG454/DG455/DG456 family of high voltage analog switches. It shares pinout compatibility with the DG411, DG412, and DG413 series but simplifies design by removing the need for a separate logic supply voltage (VL). The EY suffix specifically identifies the 16-pin narrow SOIC package configuration.

FAQ

Does the DG456 require a separate logic supply voltage?

No, the DG456 does not require a separate VL supply voltage, unlike the DG411/DG412/DG413 series.

What is the difference between DG454, DG455, and DG456?

The DG454 has all normally closed switches, the DG455 has all normally open switches, and the DG456 contains two normally closed and two normally open switches.

Can the DG456 handle signals up to the supply rails?

Yes, each switch conducts equally well in both directions and can handle an input signal range that extends to the supply voltage rails.
