Working Principles

The MC74LVX4245DTR2 operates by utilizing a combination of MOSFETs and control circuitry to perform the voltage translation. When the direction pin (DIR) is set to high, the IC translates signals from the A-side (lower voltage level) to the B-side (higher voltage level). Conversely, when the DIR pin is set to low, the translation occurs from the B-side to the A-side.

The OE (Output Enable) pins control the output buffers, allowing them to be enabled or disabled as needed. The OEn (Output Enable Negative) pins are active-low, while the OE pin is active-high.
