DG2034DN-T1-E4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2034DN-T1-E4 is a four-channel (4:1) multiplexer manufactured by Vishay Siliconix, housed in a 12-pin QFN package measuring 3 mm x 3 mm. It operates on a single power supply ranging from 1.8 V to 5.5 V and features a typical drain-source on-resistance of 2.5 Ω. The device incorporates power-down fault protection to prevent excessive current flow when the supply voltage drops to ground. Key electrical parameters include a turn-on time of 13 ns, off-isolation of -67 dB at 1 MHz, and crosstalk of -71 dB at 1 MHz. It supports an analog signal range up to the supply level and offers high ESD tolerance of 8 kV HBM.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and temperature rating. The 'DN' designation indicates the QFN-12 package variant. Confirm RoHS compliance status through the manufacturer's current product specifications before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low parasitic capacitance and minimal charge injection. Ensure the application voltage remains within the 1.8 V to 5.5 V single-supply range. Verify that the required channel count matches the four available inputs and that the 3-bit binary address control logic aligns with the system architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2034E family of power-down fault protected multiplexers. It is functionally related to other Vishay switch ICs but is distinct in its specific 4:1 configuration and QFN-12 packaging. The datasheet document number 73172 provides the definitive technical reference for this series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG2034EDQ-T1-GE3 is the MSOP-10 package equivalent within the same functional family. Cross-referencing pinouts and thermal characteristics is necessary when substituting between package types.

Analog Switches, Multiplexers, Demultiplexers FAQ

How does the device handle power-down conditions?

The DG2034E includes power-down fault protection that prevents excessive current flow when the positive supply voltage (V+) falls to ground.

What is the maximum analog signal range?

The analog signal range extends from ground (0 V) to the positive supply voltage (V+), allowing the switches to block input voltages up to the supply level when off.

What controls the selection of the active channel?

The device uses three digital control lines: two binary address lines (A0, A1) and an enable line (EN) to select one of the four inputs to connect to the common output.
