Vishay DG2034EDN-T1-GE4 Multiplexer, 4 Single 4:1, Multiplexer, 12-Pin QFN

This multiplexer is a compact analogue switch device designed to route one of four inputs to a single output in electronic systems. Intended for surface-mount assembly, it operates across a range of supply voltages and temperatures suitable for many commercial and industrial circuits. The package is small and low-profile, enabling dense board layouts while supporting multi-channel signal selection without automotive-level certification.

• Operates from 1.8V to 5.5V enabling flexible supply choices
• Maximum on-state resistance of 11Ω minimises signal loss
• Twelve electrical pins for straightforward PCB integration
• Four elements per chip reduce component count on boards
• Maximum ambient rating of 85°C supports warm operating conditions

• Suitable for multiplexing analogue sensors in instrumentation
• Used with data acquisition front-ends requiring signal routing
• Ideal for switching signals in compact consumer electronics
• Can be used for channel selection in audio routing circuits

It is designed for surface-mount installation onto compatible pads and reflow soldering processes.

The device adopts a 3x3mm QFN footprint and low 1mm height, permitting tight component placement and reduced board area.

The component is specified to operate down to -40°C and up to 85°C, so thermal management should account for elevated ambient temperatures and nearby heat sources.

It does not carry automotive-grade classification and should not be selected where automotive-specific approvals are required.
