Working Principles

The 74ACTQ652SC operates by receiving data from one bus (A) and transmitting it to another bus (B), or vice versa. The direction of data flow is controlled by the DIR input. 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 bidirectional communication.
