Working Principles
SN74LVC543ADWR operates by receiving data from one bus and transmitting it to another bus bidirectionally. The direction of data flow is controlled by the DIR pin. When DIR is set to logic high, data flows from Bus A to Bus B, and when DIR is set to logic low, data flows from Bus B to Bus A. The OE pin is used to enable or disable the outputs. When OE is set to logic high, the outputs are disabled, and when OE is set to logic low, the outputs are enabled.
