The 74F544MSA is an inverting transceiver from the 74F logic family, designed for high-speed 5V systems. It features a single channel with 3-State outputs, capable of sinking 64mA and sourcing 15mA. Operating from 4.5V to 5.5V, this transceiver is ideal for bidirectional bus interfacing, memory buffering, and industrial control applications. The 24-SSOP package provides a compact footprint.
- High Sink Current (64mA): Drives heavy loads like LED arrays and long bus lines.
- 3-State Bidirectional Operation: Enables flexible bus direction control.
- 74F High-Speed Logic: Suitable for high-frequency 5V designs.
- Compact SSOP Package: Saves board space in dense layouts.
Bidirectional Bus Transceiving
Use the 74F544MSA to interface between two 5V data buses. The 3-State outputs allow direction control and bus isolation.
High-Current Sinking for LED Displays
The 64mA sink capability makes it suitable for driving LED segments or arrays directly, reducing external driver ICs.
Memory Data Bus Buffering
Buffer and invert data lines between a CPU and memory. The high sink current handles the capacitive load of multiple memory chips.
Backplane Communication
Drive signals across a backplane in telecom or computing systems. The 3-State outputs prevent bus contention during card insertion.
Industrial Sensor Interfacing
Interface between 5V industrial sensors and a controller. The inverting function can be used to match active-low logic.
Test and Measurement Switching
Route test signals in ATE systems. The 3-State outputs enable multiplexing of multiple channels onto a shared measurement line.
