The CD74FCT244TQM is a high-speed, non-inverting buffer from Harris Corporation's 74FCT family. Operating from a 4.75V to 5.25V supply, it delivers 15mA source and 64mA sink current, making it ideal for driving heavy bus loads. Its single channel with 3-State output enables efficient bus multiplexing. Housed in a compact 20-SSOP package, this buffer is well-suited for 5V digital systems requiring signal conditioning and fan-out.
- High Sink Current (64mA): Drives capacitive loads and long traces with fast edge rates, improving signal integrity.
- 3-State Outputs: Enables bus sharing and multiplexing without external isolation components.
- Wide Temperature Range (-40°C to 85°C): Suitable for industrial and automotive environments.
- Compact SSOP Package: Saves board space while providing adequate thermal performance.
5V Bus Interfacing
Use the CD74FCT244TQM to buffer address or data lines in 5V microprocessor systems. Its 3-State outputs allow multiple devices to share the bus without contention, while the 64mA sink current handles high-capacitance traces.
Signal Buffering for Peripherals
Buffer control signals like RESET or chip-select lines to peripherals. The non-inverting buffer preserves signal polarity while providing the current needed to drive multiple inputs.
Driving High-Capacitance Loads
In systems with long PCB traces or multiple fan-outs, this buffer's high sink current (64mA) ensures fast edge rates and signal integrity, reducing propagation delays.
Memory Address Line Driver
Drive SRAM or Flash memory address lines with the CD74FCT244TQM. The 3-State outputs enable easy multiplexing between multiple memory banks or controllers.
Industrial Control Logic
In industrial PLCs or motor controllers, use this buffer to interface 5V logic signals to high-current input stages, ensuring reliable operation in noisy environments.
Test Equipment Interface
For benchtop instruments, buffer external trigger or measurement signals. The wide -40°C to 85°C temperature range supports demanding lab environments.
