Working Principles

The SN74ABTE16246DLR acts as a bidirectional buffer/driver, facilitating the transmission and reception of data between two buses. It operates using non-inverting logic, ensuring that the output signal matches the input signal. The direction of data flow is controlled by the DIR pin. When enabled, the device allows data to pass from Port A to Port B or vice versa. When disabled, the outputs are in a high-impedance state, isolating the buses.
