DG201AC/D

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201AC/D is a CMOS analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. It features four SPST-NC (Normally Closed) channels in a 16-pin DIP package. The device operates on dual supplies ranging from ±4.5V to ±18V or single supplies up to 36V. Key electrical parameters include a maximum on-resistance of 200 ohms, charge injection of 20pC, and off-state leakage current of 5nA. Switching times are specified with a maximum turn-on time of 600ns and turn-off time of 450ns. The component supports through-hole mounting and functions within an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Four independent normally closed analog switches integrated into a single package
• TTL and CMOS logic compatible control inputs for versatile interfacing
• Low off-state leakage current suitable for high-impedance signal paths

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in data acquisition systems
• Multiplexing applications requiring normally closed default states
• Audio and video signal switching circuits

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix designation when ordering, as the 'D' variant typically denotes a die form factor rather than a packaged component. Confirm RoHS compliance status directly with the manufacturer, as historical documentation indicates non-compliance for certain legacy versions. Ensure the procurement channel provides valid traceability for this discontinued or limited-supply item type.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the DG201AC/D when a normally closed configuration is required for signal integrity during power-down or fault conditions. Compare the 200-ohm on-resistance against application requirements, noting that lower resistance options exist in other series. Verify that the 600ns switching speed meets system timing constraints before finalizing the design choice.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG201 family of CMOS analog switches. It serves as a functional alternative to the DG201A variant, often distinguished by manufacturing lot or specific performance binning. The part represents a legacy solution for discrete analog switching tasks prior to the widespread adoption of ultra-low resistance modern alternatives.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed direct substitutes include the ADG201ACJ+ and DG201ACJ+. These equivalents maintain pin compatibility and similar electrical characteristics. Verify package availability, as the original DG201AC/D may be unavailable in standard retail packaging.
