The SNJ5406FK is a 6-channel inverting buffer from Texas Instruments, designed for 5V TTL systems. It features open-collector outputs capable of sinking 30mA, making it ideal for driving high-current loads or level shifting. Packaged in a 20-pin CLCC, it operates over the military temperature range of -55°C to 125°C.
- High Sink Current (30mA): Drives relays, LEDs, and other loads directly.
- Open-Collector Outputs: Enables wired-OR and level shifting to higher voltages.
- Compact CLCC Package: Suitable for space-constrained military designs.
- Military Temperature Range: Reliable in extreme environments.
High-Voltage Level Shifting
With open-collector outputs and external pull-ups, it can shift 5V logic to 30V or higher for industrial loads.
Driving High-Current Loads
Each output can sink up to 30mA, making it suitable for driving relays, solenoids, or incandescent lamps.
Wired-OR Logic Implementation
Multiple outputs can be tied together to implement OR logic for interrupt or status lines.
LED Display Drivers
Ideal for driving 7-segment displays or LED arrays with its 30mA sink capability.
Power Supply Sequencing
Use it to control power MOSFETs or transistors in power supply sequencing circuits.
Military Avionics Interfaces
Rated for -55°C to 125°C, it is suitable for avionics control systems requiring high reliability.
