DG201ACK

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ACK is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±4.5 V to ±22 V or a single supply up to 44 V. The device features an on-resistance of 85 Ω maximum and low off-leakage current of 0.1 nA. It supports TTL and CMOS logic compatibility and includes overvoltage protection for inputs and outputs. The component is housed in a 16-pin ceramic dual in-line package (CDIP) suitable for industrial and military environments.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'ACK' against the official Vishay datasheet to confirm the hermetic ceramic CDIP package variant. Ensure design requirements match the specified voltage ratings and thermal dissipation limits before ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when hermetic packaging is required for harsh environments. Compare on-resistance and leakage specifications against plastic variants if cost reduction is prioritized over radiation hardness or moisture resistance.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201 series of quad SPST analog switches. It serves as a pin-compatible replacement for older non-hermetic versions, offering improved reliability through its ceramic construction while maintaining identical electrical performance characteristics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG201B series offers pin-for-pin compatibility for non-hermetic applications. Verify that the substitute package type meets environmental constraints.
