Additional Details

The PI74LPT245LC operates at 3.3V and provides bidirectional data transfer capabilities. The 3-state outputs allow the device to be effectively disconnected from the bus, preventing bus contention in multi-drop systems. TTL compatible inputs simplify integration with various logic families. It’s commonly available in SOIC (Small Outline Integrated Circuit) packages for surface mounting on PCBs. This device is designed to minimize ground bounce and noise, ensuring clean signal transmission. A direction control pin determines the direction of data flow. The operating temperature range is typically -40°C to +85°C, making it suitable for industrial environments.
