DG2034EDN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2034EDN-T1-GE4 is a four-channel multiplexer manufactured by Vishay Siliconix, operating on a single supply voltage ranging from 1.8 V to 5.5 V. It features a maximum on-resistance of 7 Ω at 1.8 V and 4 Ω at full temperature range when powered at 2.7 V or higher. The device provides power down fault protection, preventing excessive current flow when the supply is grounded. Key dynamic parameters include a typical bandwidth of 166 MHz, turn-on time of 19 ns at 3 V, and charge injection of -2 pC. It utilizes a 12-pin QFN (3 mm x 3 mm) package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Ensure that the component meets all relevant environmental compliance standards required for the intended deployment environment before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring low parasitic capacitance and high signal integrity within a compact footprint. The wide voltage range supports battery-powered products, while the break-before-make switching action minimizes signal glitches during channel transitions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2034E family of analog switches. It is specifically configured as a 4:1 multiplexer using three-bit binary address lines (A0, A1, EN). The 'DN' suffix indicates the 12-pin QFN package variant, distinguishing it from other package options like MSOP-10.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2034EDQ-T1-GE3 serves as an alternative within the same family but utilizes an MSOP-10 package instead of the QFN-12 form factor. Verify pinout compatibility and thermal dissipation requirements when substituting packages.
