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