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. Features • Octal bidirectional bus transceiver • Eight independent data channels • Bidirectional data transfer between two buses • Direction control input for data flow selection • Three-state outputs for shared bus systems • Output enable control for bus isolation • Standard TTL logic compatibility • Single 5V supply operation • High-speed switching performance • Strong output drive capability • Suitable for microprocessor bus interfacing • DIP-20 through-hole package • Breadboard-friendly design • Reliable TTL logic performance Tutorials • 74245 Bi Directional Octal Bus Transceiver ( 74*245 74hct245 )
