DG202BDK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG202BDK is a quad single-pole single-throw (SPST) 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 ±15 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 turn-off time of 200 ns. It functions within an operating temperature range of -40°C to +85°C, dissipates up to 640 mW of power, and draws a maximum supply current of 50 µA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package variant matches design requirements. Review official datasheets for absolute maximum ratings and thermal management guidelines before integration into production hardware.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Evaluate the 85 Ohm on-resistance against signal integrity requirements. Ensure the 30 mA current limit accommodates load demands. Compare the 300 ns switching speed with system timing constraints. Verify that the SOIC-16 package dimensions fit the available PCB footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG series of CMOS analog switches. It serves as a legacy alternative to newer low-resistance variants like the DG201 or DG202BDQ. The part represents standard general-purpose switching technology used in industrial and consumer electronics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG202BDQ-E3 offers identical electrical specifications in a TSSOP-16 package. Designers must verify pin compatibility and mechanical height differences when substituting this surface-mount variant.
