DG529AK/883B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529AK/883B is a dual 4-to-1 latchable multiplexer switch manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of ±4.5V to ±20V and features a maximum on-resistance of 400 Ohms. The device utilizes an 18-CDIP (0.300 inch, 7.62mm) package for through-hole mounting. Switching times are specified with a maximum on-time of 1.5µs and off-time of 1µs. It supports single or dual power supplies ranging from 5V to 30V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SP4T configuration providing two independent 4-to-1 multiplexing channels
• Latchable input architecture maintains channel selection state without continuous control signals
• Compatible with standard logic families for direct interface
• Designed for high-reliability applications requiring robust analog signal routing

Analog Switches, Multiplexers, Demultiplexers Applications

• Data acquisition systems requiring multi-channel signal selection
• Industrial process control instrumentation
• Test and measurement equipment signal routing
• Military and aerospace electronic subsystems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix /883B indicates compliance with MIL-PRF-38535 or similar military reliability standards. Confirm that the 18-CDIP package dimensions match the target PCB footprint. Ensure the design accommodates the higher on-resistance compared to non-latchable variants. Validate supply voltage requirements against the ±4.5V to ±20V operational range.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when latched channel states are required to reduce control line count. The 400 Ohm on-resistance suits applications where signal integrity is less critical than power consumption or pin count. Consider the 1.5µs switching speed limitations for high-frequency applications. The wide supply voltage range allows flexibility in system power design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG529 series of latchable multiplexers. It serves as a ruggedized alternative to commercial-grade switches like the DG529CWN+. The /883B designation typically denotes a hermetically sealed ceramic package suitable for harsh environments. It complements other Maxim Integrated analog switches in complex signal conditioning chains.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the DG529AK/883B from other authorized distributors. Non-latchable equivalents such as the DG529CWN+ require external latching circuitry. Verify pin compatibility when replacing with generic CDIP-18 packages.
