Working Principles

The SN74LVCH16543ADGVR is a bidirectional voltage-level translator. It allows data to be transferred bidirectionally between two independent buses operating at different voltage levels. The direction of data flow is controlled by the output enable input signals (OE1 and OE2). When OE1 is low and OE2 is high, data flows from bus A to bus B. Conversely, when OE1 is high and OE2 is low, data flows from bus B to bus A.

The device uses non-inverting data paths, ensuring that the input data is reproduced accurately at the output. Schmitt-trigger inputs provide improved noise immunity, allowing reliable operation even in noisy environments. The power-up 3-state feature ensures that the outputs are in a high-impedance state during power-up and power-down, preventing any unintended signal interference.
