DG201AK/B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201AK/B is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Rochester Electronics. It features low off-state leakage current and low on-resistance, supporting wide input signal ranges. The device operates with dual supplies up to ±15V or a single supply up to 30V, ensuring TTL and CMOS logic compatibility. It is housed in a 16-pin ceramic dual in-line package (DIP), designed for applications requiring precise analog signal routing and switching.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Monolithic quad SPST architecture providing four independent analog channels
• Low off-state leakage current for high isolation performance
• Wide supply voltage range supporting dual and single supply configurations
• TTL and CMOS logic interface compatibility

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'B' against the manufacturer's datasheet to confirm pinout and electrical specifications match the design requirements. Ensure the ceramic DIP package is compatible with the target PCB footprint and assembly process. Confirm RoHS compliance status if required by the end product regulations.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel count and low leakage are critical. Compare on-resistance values with alternative switches if signal integrity at high frequencies is a concern. Verify that the operating temperature range meets the environmental conditions of the intended application.

Analog Switches, Multiplexers, Demultiplexers Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find discrete semiconductors and integrated circuits. This part is likely a continuation of production for legacy designs originally released by other manufacturers, such as Analog Devices or Harris Semiconductor, ensuring supply continuity for existing products.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG201B is documented as a pin-for-pin replacement for non-hermetic versions of the DG201A series. Verify if the 'B' suffix indicates hermeticity or updated specifications compared to the base DG201 model.
