The 54F652SDM is a high-speed, non-inverting octal bus transceiver from National Semiconductor, designed for bidirectional data communication. Operating within a 4.5V to 5.5V supply range, it features 3-State outputs and can sink up to 48mA, making it suitable for driving heavy bus loads. Housed in a durable 24-pin ceramic DIP, this component is engineered for reliable performance across the full military temperature range of -55°C to 125°C, making it a trusted choice for aerospace and high-reliability industrial applications.
- Extended Temperature Range: Operates from -55°C to 125°C, suitable for harsh military environments.
- High Drive Capability: Sinks up to 48mA, enabling direct drive of multiple loads or long bus lines.
- Ceramic Package: Provides superior thermal and mechanical stability compared to plastic packages.
- 3-State Outputs: Facilitates bus multiplexing and prevents data contention in shared-line architectures.
Military & Aerospace Bus Interfacing
The 54F652SDM's wide temperature range and ceramic package make it ideal for mission-critical data buses in avionics and defense systems, ensuring reliable bidirectional communication between processing units.
High-Speed Data Acquisition
With its 54F logic family speed, this transceiver can buffer high-frequency signals from sensors and ADCs, maintaining signal integrity in demanding industrial and test equipment.
Redundant System Controllers
3-State outputs allow multiple controllers to share a common bus. The 54F652SDM can isolate a failed controller, enabling hot-swap or redundant operation in critical infrastructure.
Legacy 5V System Interfacing
For systems still operating at 5V, this transceiver provides a robust, proven solution for connecting legacy TTL logic to newer components without level-shifting complexity.
Backplane Communication
In large rack-mounted systems, the 54F652SDM can drive long backplane traces, providing the necessary current (48mA sink) to maintain signal levels across multiple cards.
