Working Principles

The M74HCT652B1R operates by receiving input data from two separate buses, A and B. The direction control pin (DIR) determines whether the IC functions as a multiplexer or a demultiplexer. When operating as a multiplexer, the IC selects and outputs data from either bus A or B based on the control signal. In demultiplexer mode, the IC routes the input data to the appropriate output bus based on the control signal. The output enable pin (OE) enables or disables the outputs.
