DG202BDJ

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202BDJ is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates with a single supply voltage ranging from 4.5 V to 12 V or dual supplies up to ±22 V. The device features a maximum on-resistance of 85 Ohms and supports a continuous DC switch current of 30 mA. Electrical performance includes a maximum turn-on time of 300 ns and a maximum turn-off time of 200 ns. Power dissipation is rated at 470 mW, with a maximum supply current of 50 µA. It functions within an industrial temperature range of -40°C to +85°C and is housed in a 16-pin PDIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Request original datasheets and compliance documentation to confirm pinout compatibility and electrical specifications before integration into design files.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring four isolated analog paths with moderate speed requirements. Ensure the application voltage does not exceed the 12 V single-supply or ±22 V dual-supply limits. Consider thermal management if operating near the 470 mW power dissipation limit in enclosed environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of CMOS analog switches produced by Vishay Siliconix. It serves as a legacy alternative to newer generations of analog switches, offering standard DIP packaging for through-hole prototyping and manufacturing. The device is functionally similar to other quad SPST switches but is distinguished by its specific voltage ratings and package type.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public sources indicate recommended alternatives such as the DG202BDK and DG202BDQ. Verify pin compatibility and electrical parameters against the original datasheet before substitution. Note that suffix variations may denote different packages or RoHS compliance status.
