Product Summary
The SN74HC245NSR octal bus transceiver is 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.
