Working Principles

The SN74LVC1G57DRLR utilizes a combination of MOSFETs and level-shifting circuitry to translate logic levels between two voltage domains. The direction of translation is automatically determined based on the input signals. When OE (Output Enable) is high, the IC is enabled, and the logic level at A1 is translated to Y2 or vice versa. When OE is low, the IC is disabled, and the outputs are in a high-impedance state.
