DG2742DQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2742DQ-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 is housed in an SOT-23-8 surface-mount package. The device features a maximum on-resistance of 800 mOhms, with a typical switching time of 30 ns and a turn-off time of 28 ns. It supports a continuous DC switch current of 200 mA while maintaining a maximum supply current of 1 uA. The component functions within an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix T1-E3 against official Vishay documentation to confirm tape-and-reel packaging and lead-free compliance. Confirm end-of-life status through authorized distributors as availability may be restricted. Ensure the SOT-23-8 footprint matches the target PCB design before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel switch is required under 3.6 V supplies. Compare on-resistance and leakage specifications against alternative DG series parts if higher current handling or lower resistance is needed. Verify that the SOT-23-8 package dimensions fit the mechanical constraints of the assembly.

Analog Switches, Multiplexers, Demultiplexers Part Context
