Working Principles

The CY74FCT543CTSOCTG4 is a bidirectional octal bus transceiver that facilitates the transfer of data between two buses, A and B. The direction of data flow is controlled by the DIR and BDIR inputs. When DIR is high, data flows from bus A to bus B, and when DIR is low, data flows from bus B to bus A. The OE input enables or disables the outputs, allowing tristate operation.
