The MC74HCT244ADWR2G from onsemi is a high-speed octal buffer/line driver featuring non-inverting outputs with 3-State capability. Operating from 4.5V to 5.5V, it delivers 6mA sink/source current per channel, making it suitable for driving heavy loads. Its 74HCT logic family ensures TTL-compatible inputs, simplifying interfacing with legacy logic. Housed in a 20-SOIC package, it is ideal for bus-oriented systems, memory drivers, and industrial control applications requiring robust signal buffering.
- Wide Temperature Range (-55°C to 125°C): Reliable operation in extreme automotive and industrial environments.
- 3-State Outputs: Allows multiple devices to share a bus without conflict, enhancing system flexibility.
- TTL-Compatible Inputs: Direct interface with 3.3V logic when powered at 5V, simplifying mixed-voltage designs.
- High Drive Current (6mA): Capable of driving capacitive loads and multiple inputs, improving signal integrity.
Bus Interfacing in Mixed-Voltage Systems
With 3-State outputs and TTL-compatible inputs, the MC74HCT244ADWR2G is ideal for connecting 5V microcontrollers to shared data buses, preventing bus contention.
Signal Buffering for High-Fanout Clocks
Buffers multiple clock or control signals without degradation, thanks to 6mA drive capability and non-inverting logic.
Level Shifting from 3.3V to 5V
When powered at 5V, it accepts 3.3V logic inputs (TTL thresholds) and outputs 5V, enabling reliable level translation.
Industrial Control Input/Output Expansion
In PLCs and industrial controllers, it buffers sensor signals and drives indicator LEDs or relays with sufficient current.
Automotive ECU Signal Conditioning
Operates over -55°C to 125°C, suitable for under-hood automotive electronics where robust buffering is required.
Memory Address/Data Line Driving
Provides high-impedance isolation when disabled, allowing multiple memory banks to share a common bus safely.
