The MC74HCT244ADWG from onsemi is an octal non-inverting buffer with 3-State outputs, designed for 5V TTL systems. It operates from 4.5V to 5.5V and is fully TTL-compatible, making it a drop-in replacement for legacy 74LS244 devices. This buffer features 2 channels of 4 bits each, providing 8 total buffer circuits. The 3-State outputs allow for bus-oriented applications, enabling multiple devices to share a common data line. With a 6mA output current, it is suitable for driving standard TTL loads. The 74HCT family combines high-speed CMOS technology with TTL compatibility, offering low power consumption and robust performance.
- TTL-Compatible Inputs: Directly interfaces with 5V TTL logic, simplifying upgrades from older 74LS families.
- Wide Temperature Range (-55°C to 125°C): Suitable for extreme environments like automotive and aerospace.
- 3-State Outputs: Enables bus sharing and prevents data conflicts in multi-device systems.
- Low Power CMOS Technology: Reduces power consumption compared to bipolar TTL, improving system efficiency.
TTL-Compatible Signal Buffering
Use the MC74HCT244ADWG to buffer 5V TTL signals. Its TTL-compatible inputs ensure direct interfacing with legacy TTL logic without additional circuitry.
Bus Line Driving
Drive long PCB traces or backplane buses with the 3-State outputs. The 6mA drive current is sufficient for standard TTL loads and short to medium-length traces.
Memory Address Buffering
In 5V microprocessor systems, buffer address lines between the CPU and memory. The non-inverting function preserves address integrity.
Peripheral Output Expansion
Use it to drive multiple peripheral devices like LEDs or small relays. The 3-State feature allows multiple buffers to share a common output line.
Industrial Control Input/Output
In industrial PLCs, buffer sensor inputs or control outputs. The wide temperature range (-55°C to 125°C) ensures reliable operation in harsh environments.
Test and Measurement Equipment
In benchtop instruments, isolate and buffer signals between different test modules. The 3-State outputs prevent signal conflicts during testing.
