DG201BAK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201BAK/883 is a military-grade quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It features four independent channels within a 16-pin ceramic dual in-line package (CDIP). The device supports single or dual power supplies, with a maximum supply voltage of 12 V for single-ended operation and up to 22 V for dual-supply configurations. Key electrical parameters include a maximum on-resistance of 85 Ohms, a maximum switching current of 30 mA, and a maximum power dissipation of 640 mW. The unit operates within a temperature range of -55 °C to +125 °C, ensuring reliability in harsh environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix /883 indicates compliance with MIL-PRF-38534 or equivalent military standards when sourcing. Confirm that the ceramic package variant matches the required thermal and mechanical specifications for the target application. Ensure the supplier provides traceability documentation consistent with defense industry requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when military qualification and ceramic packaging are mandatory. Compare against standard plastic packages if environmental sealing is not required. Verify that the 85 Ohm on-resistance meets the signal integrity requirements of the specific circuit design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201 family of quad analog switches, which are widely recognized for their performance and longevity. The /883 suffix denotes a specific military-grade version, distinguishing it from commercial variants like the DG201BDQ. This family has been an industry standard for decades, offering a balance of speed and precision.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must match the military specification and ceramic package. Standard commercial equivalents such as DG201BDQ lack the required environmental sealing and qualification. Verify pinout compatibility before substituting with other quad SPST switches.
