DG2742DS-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2742DS-T1-E3 is a dual single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.5 V to 3.6 V. The device features a maximum on-resistance of 800 mOhms and supports a 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 is housed in an SOT-23-8 surface-mount package with a maximum power dissipation of 515 mW. The component functions within an operating temperature range of -40°C to +85°C and draws a maximum supply current of 1 µA.

• Battery-powered instrumentation and measurement devices
• Communication equipment signal path management
• Automotive infotainment system matrix switching

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

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

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel analog switch is required under 3.6 V operation. The 800 mOhm on-resistance suits low-current applications up to 200 mA. Compare against the DG2039DS-T1 if higher voltage tolerance or lower resistance is needed, noting the DG2039 supports up to 5.5 V but has higher on-resistance at low voltages.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches from Vishay Siliconix. It is functionally related to other dual SPST variants in the family, such as the DG2039DS-T1, which offers different electrical characteristics like higher voltage tolerance. The E3 suffix typically denotes lead-free and RoHS-compliant construction.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2039DS-T1 is documented as a recommended alternative. Verify compatibility regarding the 5.5 V maximum supply voltage limit and the 6 Ohm on-resistance difference compared to the DG2742's 800 mOhms.
