Working Principles

The SN74BCT29825DW is designed to shift logic-level signals between two voltage domains. It utilizes a bidirectional level-shifting mechanism, allowing seamless communication between devices operating at different voltage levels. The non-inverting nature of the device ensures that the logic state of the input signal is preserved during translation.

The IC operates by monitoring the input voltage levels and translating them to the corresponding output voltage levels based on the specified voltage ranges. The OE pin controls the output enable function, enabling or disabling the output stage of the level shifter.
