DG442LEDJ-GE3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG442LEDJ-GE3 is a quad single-pole single-throw (SPST) analog switch IC manufactured by Vishay Siliconix. It operates within a supply voltage range of 3 V to 16 V for single supplies or ±3 V to ±8 V for dual supplies. The device features a maximum on-resistance of 140 Ohms and supports a DC switch current of 10 mA. Power dissipation is rated at 650 mW, with a maximum power supply current of 1 uA. Switching times include a maximum turn-on time of 210 ns and a maximum turn-off time of 130 ns. It functions in temperatures from -40°C to +85°C and is housed in a 16-pin SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix JE3 against the official Vishay datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the SOIC-16 package dimensions align with the PCB footprint. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration is required with moderate on-resistance. Compare the 140 Ohm on-resistance and 210 ns switching speed against application needs. Consider the DG442LDY-GE3 variant if lower on-resistance and faster switching are necessary, noting the package remains consistent.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG44x series of CMOS analog switches from Vishay Siliconix. It shares functional similarities with other members like the DG441 and DG442 variants, differing primarily in channel count or performance metrics. The LEDJ suffix indicates a specific tape and reel packaging option within the broader DG442 family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG442LDY-GE3 is documented as a recommended alternative with similar functionality but different electrical parameters. Verify compatibility regarding on-resistance and switching speeds before substitution.
