Overview
The DG509ADJ+ is a monolithic CMOS analog multiplexer featuring a differential 4-channel (2-of-8) configuration. It operates from dual power supplies ranging from ±4.5V to ±18V, with a typical operating voltage of ±15V. The device guarantees break-before-make switching and includes latchup-proof construction. Key electrical parameters include a maximum drain-source on-resistance of 550 Ohms at ±15V, a transition time of 1.0 µs, and an enable turn-on time of 1.5 µs. It is housed in a 16-pin Plastic DIP package and supports an extended industrial temperature range from -40°C to +85°C.
Feature Summary

Procurement Notes
Verify the component authenticity by checking for the Analog Devices or Maxim Integrated branding and confirming the specific ordering suffix matches the requested package type. Ensure the datasheet revision aligns with current manufacturing standards. Cross-reference the part number against official distributor catalogs to confirm availability status and compliance with environmental regulations such as RoHS requirements before finalizing procurement orders.
Selection Notes
Select the DG509ADJ+ when a differential multiplexing solution is required for applications needing symmetric operation across multiple channels. This model is suitable for designs requiring robust performance within the -40°C to +85°C temperature range. Engineers should verify that the system's power supply constraints fall within the ±4.5V to ±18V operational window and ensure that the logic interface levels are compatible with the TTL/CMOS input specifications provided in the datasheet.
Part Context
The DG509ADJ+ belongs to the DG508A/DG509A series of monolithic CMOS analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. While the DG508A variant provides a single-ended 8-channel configuration, the DG509A specifically offers a differential 4-channel setup. Both devices share similar architectural features, including low power consumption and high-speed switching capabilities, making them suitable replacements for legacy industry-standard components in modern electronic designs.
Replacement Considerations
Direct replacement options include other variants within the DG509A family, such as DG509ACJ or DG509ABK, depending on the required temperature range and package style. Verify pin compatibility and electrical characteristics against the original design specifications to ensure seamless integration without circuit modification.
