The MC74HCT244AWD from onsemi is a dual non-inverting buffer with 3-State outputs, designed for 5V TTL-compatible systems. Operating from 4.5V to 5.5V, it provides 6mA of output drive per channel. The TTL-compatible inputs make it ideal for interfacing with legacy TTL logic. The 3-State outputs enable bus-oriented applications. With a wide temperature range of -55°C to 125°C, it is suitable for demanding industrial and automotive applications.
- TTL-Compatible Inputs: Directly interfaces with legacy 5V TTL logic without extra components.
- 3-State Outputs: Enables bus sharing and prevents data corruption in multi-device systems.
- Wide Temperature Range (-55°C to 125°C): Suitable for harsh environments.
- Standard 5V Operation: Ideal for existing 5V system designs.
TTL-to-CMOS Interfacing
The 74HCT family is specifically designed with TTL-compatible input thresholds. Use the MC74HCT244AWD to interface legacy 5V TTL logic directly to CMOS logic without additional level-shifting circuitry.
Microprocessor Bus Isolation
Isolate the microprocessor data/address bus from peripherals. The 3-State outputs allow the CPU to disconnect from the bus when not actively communicating, preventing bus contention.
5V System Signal Buffering
Buffer weak 5V logic signals from sensors, switches, or other low-drive sources. The 6mA output drive capability ensures reliable signal transmission over moderate trace lengths.
Memory Module Address Driving
Drive multiple memory chips (SRAM/Flash) from a single address bus. The buffer provides the necessary fan-out and drive strength to handle multiple loads.
Industrial PLC I/O Modules
In programmable logic controllers, this buffer can interface between the 5V logic core and external I/O connectors, providing robust signal conditioning in industrial environments.
Test Equipment Signal Routing
Use the 3-State outputs to route test signals to different measurement points. The high-impedance state allows multiple test points to share a single measurement channel.
