SN74HC245N 74HC245 Octal Bus Transceiver with Tri-State Outputs - CMOS - DIP20

This octal bus transceiver has been designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements.

The device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
