The 54F651SDMQB is an octal inverting transceiver from National Semiconductor's 54F logic family. It features 8-bit bidirectional data flow with 3-State outputs, operating from a 4.5V to 5.5V supply. With output drive capability of 12mA source and 48mA sink, it provides robust performance for high-speed bus applications. The device is designed for the extended temperature range of -55°C to 125°C and is packaged in a 24-pin CDIP, making it suitable for military and aerospace environments where reliability is paramount.
- Extended Temperature Range (-55°C to 125°C): Meets stringent military and aerospace requirements.
- High-Speed 54F Logic: Ensures minimal propagation delay for time-critical applications.
- 3-State Outputs: Provides bus isolation and multiplexing capabilities.
- Ceramic DIP Package: Offers superior thermal and mechanical stability in harsh environments.
Military/Aerospace Data Buses
With a -55°C to 125°C temperature range and ceramic package, it is ideal for mission-critical data buses in avionics and satellite systems.
High-Speed Signal Routing
The 54F family's fast propagation delay makes it suitable for routing high-frequency signals in radar and communication systems.
Bidirectional Buffering in Embedded Controllers
It can buffer the data bus between a microcontroller and multiple peripherals, providing 3-State isolation when needed.
Test and Measurement Equipment
In ATE (Automated Test Equipment), it can switch and buffer test vectors to device-under-test pins at high speeds.
Industrial Process Control
Its rugged temperature range allows reliable operation in steel mills or chemical plants where ambient temperatures are extreme.
Redundant System Interconnects
In fault-tolerant systems, the 3-State outputs allow one controller to drive a bus while another is in high-impedance mode.
