DG201ADY

Analog Switches, Multiplexers, Demultiplexers Overview

The DG201ADY is a quad single-pole single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features normally closed contacts and operates with dual power supplies ranging from ±4.5V to ±18V. The device utilizes monolithic low-power CMOS technology, ensuring compatibility with both TTL and CMOS logic levels without requiring a separate VL supply. Key electrical specifications include a maximum turn-on time of 600ns and a maximum turn-off time of 450ns at +25°C. The package configuration is a 16-pin Small Outline (SO) integrated circuit.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed nonlatching operation when power supplies are disconnected while input signals remain connected
• Elimination of the third VL power supply required for original manufacturer versions
• Monolithic low-power CMOS design suitable for portable applications
• CMOS and TTL logic compatible control inputs

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required temperature range and package type. Check for RoHS compliance status as older manufacturing runs may differ. Ensure proper handling procedures are followed due to the sensitivity of CMOS structures to electrostatic discharge during storage and installation.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring normally closed signal paths with fast switching speeds. Compare against the DG211 variant if slower switching times are acceptable but lower on-resistance variation is needed. Consider the operating temperature range of -40°C to +85°C for industrial environments. Verify that the dual supply voltage requirements align with the system power architecture before integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG201A/DG211 family of quad SPST CMOS analog switches. The DG201A series is distinguished by faster switching characteristics compared to the DG211. The 'DY' suffix indicates a 16-pin SO package with an extended industrial temperature range. This family replaces earlier discrete solutions in signal routing and multiplexing tasks.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes within the same family include the DG211DY, which shares the package but has different switching speeds. Other variants like the DG201ACJ offer the same functionality in a Plastic DIP package. Cross-referencing datasheets is essential to ensure pinout compatibility and electrical parameter alignment.
