DG2034EDQ-T1-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2034EDQ-T1-GE3 is a four-channel multiplexer manufactured by Vishay Siliconix, operating on a single power supply ranging from 1.8 V to 5.5 V. It features a maximum drain-source on-resistance of 11 Ω at room temperature and up to 11 Ω across the full industrial temperature range (-40 °C to +85 °C). The device provides power down fault protection, ensuring that excessive current flow is prevented when the supply voltage is grounded. It utilizes a 3-bit binary address logic (A0, A1, EN) to select one of four inputs for a common output. The component is housed in an MSOP-10 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the package type and environmental compliance status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the document number 73172 with the latest revision to confirm technical specifications have not changed. Confirm RoHS compliance details are consistent with project requirements before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring low parasitic capacitance and minimal charge injection. Verify that the required analog signal range falls within the 0 V to V+ limits. Ensure the design accommodates the specified turn-on and turn-off times under the target load conditions. Check that the power dissipation limits of the MSOP-10 package are sufficient for the expected thermal environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG2034E family of power-down fault protected multiplexers. It is functionally compatible with other devices in the series but differs in packaging. The 'D' suffix indicates the MSOP-10 package variant, while other suffixes may denote QFN packages. The 'E3' suffix typically denotes lead-free and RoHS compliance, though verification against the datasheet is recommended.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG2034EDN-T1-GE4 is a confirmed substitute part number available in a 12-pin QFN (3 mm x 3 mm) package. Both parts share identical electrical characteristics and functionality. Designers must account for the physical footprint differences between the MSOP-10 and QFN-12 packages when substituting.
