Working Principles

The SN74LVC2952APWT utilizes a combination of MOSFETs and control circuitry to achieve bidirectional voltage translation. The OE (Output Enable) pins control the direction of translation, allowing data to flow from one voltage domain to another. When the OE pin is low, the A port is enabled, and data can be transmitted from the A side to the B side. Conversely, when the OE pin is high, the B port is enabled, enabling data transmission from the B side to the A side.
