SN74ALS639A, SN74AS638A, OCTAL BUS TRANSCEIVERS

These octal bus transceivers are designed for asynchronous two-way communication between open-collector and 3-state buses.

The devices transmit data from the A bus (open-collector) to the B bus (3 state) or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) inpu
