DG2743DS-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2743DS-T1-E3 is a dual single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.5 V to 3.6 V and features an SOT-23-8 surface-mount package. The device provides two independent channels with a maximum on-resistance of 800 mOhms and supports a continuous DC switch current of 200 mA. Switching performance includes a maximum turn-on time of 30 ns and a maximum turn-off time of 28 ns. It functions within a temperature range of -40°C to +85°C, drawing a maximum supply current of 1 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T1' against the manufacturer's official documentation to confirm reel packaging specifications. Confirm RoHS compliance status via the latest datasheet as regulatory requirements may evolve. Ensure the component source matches Vishay / Siliconix directly or through authorized distribution channels to prevent counterfeit risks.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low-voltage operation below 3.6 V is required. Compare the 800 mOhm on-resistance against system signal integrity requirements. Verify that the SOT-23-8 footprint aligns with existing PCB layout constraints. Consider thermal dissipation limits if operating near maximum current ratings.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches from Vishay Siliconix. It shares the same pinout and general electrical characteristics as the DG2741DS-T1-E3, differing primarily in manufacturing lot or minor process revisions. Both components utilize the same SOT-23-8 package and are designed for low-voltage applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2741DS-T1-E3 is documented as a recommended alternative with identical functional parameters. Verify pin compatibility and package dimensions before substitution.
