74F645 - Octal Bus Transceiver

Fairchild (now onsemi)

Datasheet Details

These devices are octal bus transceivers designed for asynchronous two-way data flow between the A and B busses.

Both busses are capable of sinking 64 mA, have 3STATE outputs, and a common output enable pin.

The direction of data flow is determined by the transmit/receive (T/R) input.
