Overview
The DG509AAK/883 is a dual 4:1 CMOS analog multiplexer/demultiplexer manufactured by Vishay Siliconix. It features two independent SP4T switch configurations within a single package. The device operates with a supply voltage range of 5 V to 20 V and supports dual power supplies. Key electrical parameters include a maximum on-resistance of 400 Ohms, a propagation delay time of 1000 ns, and a power dissipation rating of 900 mW. It functions reliably across an operating temperature range from -55°C to +125°C.
Feature Summary
- Dual independent 4:1 analog signal routing capability
- High-temperature operation up to 125°C
- Wide single or dual supply voltage compatibility
- Military-grade ceramic DIP packaging
Applications
- Data acquisition systems requiring high reliability
- Test and measurement instrumentation
- Industrial process control applications
- Aerospace and defense electronic circuits
Procurement Notes
Verify the specific suffix and revision level against the official Vishay datasheet to ensure compliance with military specifications (MIL-PRF-38534). Confirm that the ceramic package integrity meets required environmental standards for the intended deployment environment.
Selection Notes
Select this component when dual isolated 4-channel switching is required in harsh environments. Consider the 1000 ns propagation delay as a limiting factor for high-speed data paths. Ensure the 400 Ohm on-resistance aligns with signal integrity requirements for the specific application bandwidth.
Part Context
This part belongs to the DG509B series of CMOS analog switches. It provides a robust solution for signal routing in critical infrastructure. The ceramic construction offers superior thermal stability and hermetic sealing compared to standard plastic packages, making it suitable for long-life mission-critical electronics.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. Evaluate generic CMOS multiplexers only if military specifications and hermetic sealing requirements can be relaxed.
