DG529CWN+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529CWN+ is an 8-channel, differential CMOS multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It features on-board address and control latches to simplify microprocessor-based designs. The device supports dual supplies from ±4.5V to ±20V or a single supply from +5V to +30V. Key electrical parameters include a maximum on-resistance of 450Ω, a switching time of 1.5µs, and a break-before-make interval of 0.2µs. It operates within a temperature range of 0°C to +70°C and is housed in an 18-pin Wide SO package.

• Avionics and military systems
• Microprocessor-controlled systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CWN against official documentation to confirm the 18-pin Wide SOIC package and commercial temperature range. Ensure compatibility with existing PCB footprints and thermal management strategies for the specified power dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a differential 2-of-8 multiplexer configuration is required. Verify that the system requires latchable address inputs to minimize microprocessor bus overhead. Confirm that the analog signal range fits within the supported single or dual supply voltage constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG528/DG529 family of monolithic CMOS multiplexers. The DG529 variant specifically provides two independent 4-to-1 differential channels (totaling 8 single-ended paths), whereas the DG528 offers a single 8-to-1 path. Both share identical pinouts and control logic.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitutes include the industry-standard DG529 and the ADG529. These parts are pin and electrically compatible with the DG529CWN+. Verify that any replacement maintains the same package type and temperature rating.
