Working Principles

The 74LV1T126GWH operates by receiving logic level signals on its input pins (A1, B1, A2, B2, A3, B3, A4, B4) and shifting them to the corresponding output pin (Y). The OE (Output Enable) pin controls the output state, allowing the IC to be enabled or disabled as needed. When the OE pin is low, the output is active, and when it is high, the output is in a high-impedance state.
