DG201BAK

Analog Switches, Multiplexers, Demultiplexers Overview

The Vishay Siliconix DG201BAK is a quad single-pole single-throw (SPST) analog switch IC housed in a 16-pin ceramic dual in-line package (CDIP). It operates on single or dual power supplies ranging from 4.5V to 22V for dual configurations, or up to 12V for single supply. The device features a maximum on-resistance of 85 Ohms and supports a continuous DC switch current of 30 mA. Switching times are specified at a maximum of 300 ns for turn-on and 200 ns for turn-off. Power dissipation reaches 900 mW, with a maximum supply current of 50 uA.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm pinout compatibility and material composition. Ensure the procurement source provides valid traceability records for ceramic packages. Confirm that the delivered units match the exact part number specifications regarding voltage ratings and thermal characteristics before integration into final assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high reliability and hermetic sealing are required for analog signal switching. The CDIP package offers superior thermal performance compared to plastic equivalents. Verify that the system's power supply range aligns with the 4.5V to 22V dual supply capability. Consider the 85 Ohm on-resistance limit for signal integrity requirements in the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

The DG201BAK belongs to the DG series of analog switches manufactured by Vishay Siliconix. This series is characterized by CMOS technology offering low power consumption and high speed. The BA variant specifically denotes the ceramic DIP package option, distinguishing it from plastic surface-mount or through-hole alternatives within the same functional family.
