DG442LEDY-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442LEDY-GE3 is a monolithic quad single-pole-single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features a normally open configuration and operates on single supplies from 3 V to 16 V or dual supplies of ±3 V to ±8 V. The device provides low on-resistance with a typical value of 16 Ω and maximum of 35 Ω at room temperature, alongside fast switching speeds with a typical turn-on time of 18 ns. It exhibits low charge injection of less than 8 pC and minimal leakage current. Packaged in a 16-lead narrow body SOIC for surface-mount installation, it supports an operating temperature range of -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific material categorization documentation if required for regulatory adherence. Ensure the package type matches the intended PCB footprint design specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally open state is required for the analog switches. Compare against the DG441LE series if a normally closed configuration is needed instead. Verify that the supply voltage requirements align with the specified 3 V to 16 V single or ±3 V to ±8 V dual supply ranges.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG441LE/DG442LE family of precision monolithic quad SPST CMOS analog switches. It shares core electrical characteristics with the DG441LE but differs in its default logic state, offering a normally open function compared to the normally closed DG441LE. Both are designed for low error switching applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG441LEDY-GE3: Identical electrical specifications but features a normally closed configuration instead of normally open.
