DGQ4053EEQ-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DGQ4053EEQ-T1-GE4 is a triple SPDT analog multiplexer manufactured by Vishay Siliconix. It integrates three independent 2-to-1 channels within a 16-pin TSSOP package. 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 maximum on-resistance of 103 Ω at 12 V, typical charge injection of 0.3 pC, and low off-state leakage below 50 pA. It supports bi-directional rail-to-rail signal switching with an enable pin for global control. Operating temperatures range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'EQ-T1-GE4' against official documentation to confirm the tape-and-reel packaging format and extended temperature rating. Ensure that the ordering configuration matches the required marking code Q4053E. Cross-reference the document revision date to validate current specifications before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring three independent SPDT switches in a single package. It is appropriate for applications needing low charge injection and high bandwidth. Verify that the system logic levels are compatible with the guaranteed 2 V high limit at 5 V operation. Confirm that the thermal dissipation requirements fit within the 16-pin TSSOP package constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DGQ405xE family alongside the DGQ4051E (8-channel) and DGQ4052E (dual 4-channel). All variants share identical pinouts and core CMOS technology but differ in channel count. The DGQ4053E specifically provides three isolated 2:1 paths, offering a distinct topology compared to the higher-density options in the series.
