The MC74HCT245ADTR2G-Q is a high-speed octal bus transceiver from onsemi, designed for 5V systems. It features non-inverting, 3-State outputs and 8 bidirectional channels. Operating from 4.5V to 5.5V, it provides 6mA source and sink current, ensuring robust signal drive. Its HCT logic family guarantees TTL-compatible inputs, making it ideal for interfacing with legacy logic. Typical applications include bus interfacing, data buffering, and signal regeneration in industrial and automotive systems.
- TTL-Compatible Inputs: Directly interfaces with 5V TTL logic without extra level shifting, simplifying design.
- 3-State Outputs: Allows multiple devices to share a bus safely, preventing data corruption.
- Wide Temperature Range (-55°C to 125°C): Suitable for extreme automotive and industrial environments.
- High-Speed HCT Technology: Provides fast propagation delays while maintaining low power consumption.
5V TTL Bus Interfacing
Use the MC74HCT245ADTR2G-Q to interface between 5V microcontrollers and legacy TTL logic buses. Its HCT family ensures TTL-compatible input thresholds, guaranteeing reliable logic level detection.
Bidirectional Data Buffering
In memory or peripheral systems, this transceiver buffers bidirectional data lines. The 3-State outputs prevent bus contention by allowing multiple devices to share the same data bus.
Signal Level Translation (5V to 5V)
For systems requiring signal regeneration without level shifting, this buffer provides clean, non-inverting signal restoration, improving noise margins and driving capability.
Industrial Control I/O Expansion
In PLCs and industrial controllers, the 3-State outputs enable efficient I/O expansion. The wide -55°C to 125°C temperature range suits harsh environments.
Automotive ECU Communication
