Working Principles

The SN74HC623DWRE4 is an octal bus transceiver that enables bidirectional data transfer between two buses. The direction of data flow is controlled by the DIR pin, while the OE pin allows enabling or disabling the output. When the DIR pin is set to transmit mode, data from the A bus is transferred to the B bus. In receive mode, data from the B bus is transferred to the A bus.
