Description
Description
The 74245 is a TTL logic integrated circuit designed to provide eight bidirectional data channels for efficient communication between two separate 8-bit buses. It features direction control for selecting the data flow path and output enable control for isolating the bus when needed. Its three-state outputs make it ideal for shared bus architectures commonly found in microprocessor and memory systems. Operating on a standard 5V TTL supply, the 74245 is widely used for bus interfacing, signal buffering, and digital system expansion.
