Working Principles
The 74LVT640D,112 is designed to translate logic-level signals between two voltage domains. It utilizes a bidirectional voltage translation scheme, allowing seamless communication between devices operating at different voltage levels. The direction of translation is controlled by the OE# (Output Enable) pin. When the OE# pin is low, the device is in the active state, enabling bidirectional signal translation. Conversely, when the OE# pin is high, the device is in the high-impedance state, isolating the input and output sides.
