DG529AK/883

Analog Switches, Multiplexers, Demultiplexers Overview

The DG529AK/883 is a high-reliability analog multiplexer manufactured by Vishay Siliconix, designed for military and aerospace applications. It features an 18-lead ceramic dual in-line package (CDIP) with hermetic sealing. The device integrates latchable single-ended or differential analog switching capabilities. Key electrical parameters include a maximum on-resistance of 400 Ohms and a supply voltage range supporting dual supplies up to 15 V. Operating temperatures span from -55°C to +125°C, ensuring stability in extreme environments.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Hermetically sealed ceramic construction for radiation and moisture resistance
• Latchable output state retention for signal integrity during power transitions
• Configurable as single-ended or differential multiplexing channels

Analog Switches, Multiplexers, Demultiplexers Applications

• Military avionics signal routing
• Aerospace telemetry data acquisition
• Harsh environment sensor interfacing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the authenticity of the 883 suffix certification, which denotes compliance with MIL-PRF-38534 standards. Confirm that the package is genuine ceramic CDIP rather than plastic alternatives. Request full lot traceability and material composition reports. Ensure the component meets specific reliability screening requirements for defense contracts. Validate that the latchable functionality is intact and not compromised by previous handling.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when hermetic sealing and latchable outputs are mandatory for system reliability. It is suitable for designs requiring operation across wide temperature ranges without thermal degradation. Consider the higher on-resistance compared to standard CMOS switches when designing low-impedance signal paths. Evaluate the physical size constraints of the 18-lead ceramic package against available board space.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG series of analog switches, specifically tailored for high-reliability sectors. Unlike commercial variants, it undergoes rigorous screening processes. The AK/883 designation indicates a specific grade within the Vishay portfolio focused on long-term stability and environmental resilience.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG429DJ-E3 offers similar multiplexing functions but lacks hermetic sealing and latchable outputs. Verify if the loss of radiation hardness and ceramic packaging is acceptable for the application.
