Overview
The DG409AK/883P is a high-reliability, dual 4-to-1 multiplexer switch integrated circuit manufactured by Vishay Siliconix. Designed for military and aerospace applications, it features four independent analog switches arranged in a 2x4 configuration within a 16-pin ceramic dual in-line package (CDIP). The device supports wide supply voltage ranges, including single supplies from 5 V to 36 V or dual supplies up to ±20 V. It exhibits a maximum on-resistance of 100 Ohms, with turn-on and turn-off times capped at 150 ns. Operating temperatures span from -55°C to +125°C, ensuring robust performance in extreme environments while maintaining low power dissipation characteristics.
Feature Summary
- Military-grade construction utilizing hermetic ceramic packaging for enhanced environmental protection
- Dual 4-to-1 multiplexer architecture providing four independent signal routing channels
- Wide operational temperature range suitable for harsh industrial and defense conditions
Applications
- Aerospace telemetry systems requiring reliable signal switching
- Military instrumentation and data acquisition equipment
- Harsh environment test and measurement setups
Procurement Notes
Verify that the specific suffix /883P confirms compliance with MIL-PRF-38534 or equivalent military reliability standards. Confirm that the ceramic package provides the necessary hermetic seal for your application's environmental requirements. Ensure that the manufacturer documentation explicitly lists this part as qualified for space or defense use before procurement.
Selection Notes
Select this component when high reliability and radiation hardness are critical compared to standard commercial grade parts. Compare the 100 Ohm on-resistance against lower resistance alternatives if signal integrity for high-current paths is a priority. Verify that the CDIP-16 footprint matches your existing board layout constraints and that the wide temperature range aligns with your system's thermal design specifications.
Part Context
This part belongs to the DG409 series of CMOS analog multiplexers, distinguished by its military qualification. While functionally similar to the commercial DG409AK, the /883P designation indicates adherence to stricter manufacturing controls and testing protocols defined by military specifications. It serves as a ruggedized alternative for designs where standard plastic packages would fail under vibration or thermal stress.
Replacement Considerations
Direct replacements include the DG409AK for non-military applications, though package and reliability differences exist. For surface mount needs, consider the DG409DY-T1, noting the change from ceramic DIP to SOIC package. Always verify pin compatibility and electrical parameter tolerances before substituting.
