Working Principles

The SN74LVCC3245APWRG4 operates by translating voltage levels between two sets of I/O pins (A1-A24 and B1-B24) based on the direction control input (DIR). When DIR is set to logic high, the A-side pins are connected to the B-side pins, allowing bi-directional communication. Conversely, when DIR is set to logic low, the B-side pins are connected to the A-side pins.

The output enable input (OE) controls the tri-state output buffers, enabling or disabling the transmission of data. When OE is set to logic high, the outputs are in a high-impedance state, isolating the device from the bus.
