The SN74LS645-1N is an octal Bus Transceiver designed for asynchronous two-way communication between data buses. The devices transmit data from the A bus to the B bus or from the B bus to the A bus depending upon the level at the direction control (DIR) input. The enable input (G\\) can be used to disable the device so the buses are effectively isolated.
● Hysteresis at bus inputs improves noise margins
● Choice of true or inverting logic
● 3-state outputs
