Working Principles

The MC74LVX244MG is a logic level shifter that operates by taking in low-voltage signals from the input pins and shifting them to higher voltage levels at the output pins. It uses non-inverting buffers to amplify and transmit the signals without changing their logic state. The output enable pin (OE) controls the output state, allowing for tri-state operation when disabled.
