Octal bus transceiver; 3-state

The 74ALVC245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74ALVC245 features an output enable input (OE) for easy cascading and send/receive input (DIR) for direction control. OE controls the outputs, so that the buses are effectively isolated.
