The DM5416J-MIL is a monolithic hex inverting buffer from National Semiconductor, designed for 5V TTL logic systems. It features six independent open-collector outputs capable of sinking up to 30mA, making it ideal for driving loads or implementing wired-OR logic. Operating across the full military temperature range of -55°C to 125°C, this buffer is housed in a robust 14-pin ceramic DIP, ensuring reliability in demanding environments. Its inverting function and high current-sink capability make it a versatile choice for signal buffering, level shifting, and load driving in industrial and aerospace applications.
- High Current Sink (30mA): Directly drives LEDs, relays, or lamps without additional transistors, simplifying output stages.
- Open-Collector Outputs: Enables wired-OR bus connections and flexible level shifting to higher voltages.
- Military Temperature Range (-55°C to 125°C): Guarantees operation in extreme environments for defense and aerospace.
- Ceramic DIP Package: Provides superior thermal and mechanical stability compared to plastic packages.
Wired-OR Bus Interfacing
The open-collector outputs allow multiple DM5416J-MIL devices to be connected to a single bus line, enabling a wired-OR configuration commonly used in interrupt or request lines.
Level Shifting for Legacy Systems
With external pull-up resistors, the open-collector output can shift signal levels from 5V logic to higher voltages (e.g., 12V or 24V) for interfacing with older industrial equipment.
Driving High-Current Loads
Each output can sink up to 30mA, making it suitable for driving LEDs, relays, or small lamps directly, with the current limited by an external resistor.
Inverting Signal Buffering
Use it to invert and buffer digital signals in 5V TTL systems, providing increased fan-out to drive multiple downstream logic inputs.
Military & Aerospace Control Logic
Rated for -55°C to 125°C, this ceramic-package IC is suitable for harsh environments like avionics or military control systems requiring reliable 5V logic.
Glue Logic in Industrial Controllers
It can serve as simple glue logic to interface between different 5V logic families or to create active-low control signals in PLCs and industrial controllers.
