Working Principles

The SN74CBT3345DGVR is a bidirectional transceiver that allows data transmission between two buses. It operates by controlling the direction of data flow using the DIR pin. When DIR is set to logic low, data flows from the A bus to the B bus, and when DIR is set to logic high, data flows in the opposite direction.

The OE pin enables or disables the outputs of the device. When OE is set to logic low, the outputs are enabled, allowing data transmission. Conversely, when OE is set to logic high, the outputs are disabled, effectively isolating the device from the buses.
