74245 Octal Bus Transceiver Logic IC

The 74245 is a TTL logic IC that integrates eight bidirectional bus transceivers in a single package.
It enables controlled data transfer between two 8-bit buses using direction and enable control inputs.
The device operates from a single 5 V supply and is compatible with standard TTL logic levels.
Three-state outputs allow direct connection to shared system buses.
Typical applications include data bus interfacing, microprocessor systems, and bidirectional signal buffering.
