Working Principles

The SN74CBT16245DGVR is a bidirectional bus switch that allows for the multiplexing and demultiplexing of digital signals. It operates by controlling the direction of data flow between multiple input/output channels. The OE pin enables or disables the output, while the DIR pin determines the direction of data transmission. When the OE pin is low and the DIR pin is set accordingly, data can be transmitted bidirectionally between the selected channel and the I/O pins.
