The MC74HCT244ADTR2G-Q is a dual-channel non-inverting buffer from the HCT logic family. It operates from 4.5V to 5.5V and features 3-State outputs. With 6mA source/sink capability, it is ideal for driving LEDs and small loads. Its wide temperature range (-55°C to 125°C) makes it suitable for automotive and industrial applications. Available in a 20-TSSOP package.
- Wide Temperature Range (-55°C to 125°C): Suitable for harsh automotive and industrial environments.
- TTL-Compatible Inputs: Can interface with 3.3V logic in mixed-voltage systems.
- 3-State Outputs: Enables bus sharing and isolation.
- Dual-Channel Design: Provides two independent buffers in one package, saving board space.
Microcontroller I/O Expansion
Use the MC74HCT244A to buffer and drive multiple LEDs or relays from a microcontroller's I/O pins. The 6mA drive capability is sufficient for standard LEDs and small loads.
Level Shifting from 3.3V to 5V
Although HCT is TTL-compatible, it can be used to interface 3.3V logic signals to 5V TTL systems, as its input thresholds accept TTL levels.
Bus Isolation in Mixed-Voltage Systems
In systems with multiple 5V peripherals, this buffer provides 3-State outputs to isolate devices when not in use, preventing bus contention.
Automotive ECU Signal Conditioning
With a wide temperature range (-55°C to 125°C), this buffer is suitable for automotive electronic control units (ECUs) to buffer sensor signals and control outputs.
Industrial Sensor Interfacing
In industrial controls, this IC can buffer signals from sensors to a PLC or controller, providing clean, non-inverted signals with adequate drive strength.
