The MC74HCT244A from onsemi is a dual 4-bit non-inverting buffer from the 74HCT family. It features 3-state outputs that can be disabled for bus-oriented applications. Operating from 4.5V to 5.5V, it is designed for 5V systems. The buffer can source and sink 6mA of current, providing adequate drive for multiple loads. Its TTL-compatible inputs allow for easy interfacing with legacy logic. It is available in a 20-SOIC package.
- 8 Buffers in One Package: Provides a compact solution for buffering multiple signals.
- 3-State Outputs: Enables bus sharing and isolation in complex systems.
- TTL-Compatible Inputs: Simplifies interfacing with 5V TTL logic.
- Wide Temperature Range: Operates from -55°C to 125°C, suitable for harsh environments.
Memory Address Buffering
In microprocessor systems, the MC74HCT244A can buffer address lines, providing the necessary drive current to reach multiple memory chips without signal degradation.
Data Bus Isolation
The 3-state outputs allow the buffer to isolate the data bus from the processor when not in use, preventing bus contention and improving system reliability.
Driving Multiple Peripheral Loads
With 6mA drive capability per output, this buffer can drive multiple TTL or CMOS inputs, ensuring clean signals across a fan-out of several devices.
Industrial Control Outputs
In industrial PLCs, this buffer can drive control signals to relays, LEDs, and other actuators, providing a robust interface between the logic controller and the field devices.
Automotive ECU Interfaces
In automotive ECUs, the 74HCT family's TTL-compatible inputs make it easy to interface with various sensors and actuators, while the 3-state outputs allow for flexible signal routing.
