DG456EQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG456EQ-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 a typical on-resistance of 4 ohms and a maximum rating of 44 volts. The device supports dual supplies of ±5 V to ±15 V or a single supply up to 12 V, enabling an analog signal range extending to the supply rails. It operates within a temperature range of -40 °C to +125 °C and is housed in a 16-pin TSSOP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent SPST switches with low on-resistance for minimal signal distortion
• High voltage capability supporting analog signals up to ±15 V
• TTL/CMOS compatible digital logic inputs without requiring a separate VL supply
• Fast switching speeds suitable for video and audio signal routing

Analog Switches, Multiplexers, Demultiplexers Applications

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

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EQ' confirms the 16-pin TSSOP package variant when sourcing replacements. Ensure the E3 designation is recognized as the lead-free and RoHS compliant version required for environmental standards. Cross-reference the manufacturer part number against official distributor catalogs to confirm current production status and availability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high voltage handling and low distortion are critical requirements. The DG456 configuration provides two normally open and two normally closed switches, offering flexibility compared to uniform NC or NO variants. Verify that the operating voltage does not exceed the 44 V absolute maximum rating and that the thermal dissipation limits of the TSSOP package are respected.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG454/DG455/DG456 series of high voltage analog switches. It shares pin compatibility with the DG411, DG412, and DG413 series but eliminates the need for a separate logic supply voltage. The EQ suffix specifically identifies the thin-shrink small outline package (TSSOP) form factor used in space-constrained designs.
