Working Principles

The SN74LVC2G126YEPR is a dual bus buffer gate that operates by receiving input signals on the A and B pins. The logic level of these inputs determines the output state of the Y pin. When the OE pin is low, the outputs are enabled and mirror the inputs. Conversely, when the OE pin is high, the outputs are disabled and enter a high-impedance state.

The IC is designed to provide voltage level shifting between different logic families, allowing seamless integration of devices with varying voltage requirements. It also acts as a buffer, preventing signal degradation during transmission.
