Working Principles

The 74LVC1G126DBVTG4 is a single bus buffer gate with 3-state output. It operates as a level shifter, allowing bidirectional communication between devices operating at different voltage levels. The device uses low-voltage CMOS technology, enabling compatibility with both 3.3V and 5V logic levels.

When the OE (Output Enable) pin is set to a logic high state, the output Y is enabled and follows the input A. Conversely, when the OE pin is set to a logic low state, the output Y is in a high-impedance state, effectively disconnecting it from the circuit.

The device's small size and low power consumption make it suitable for portable and battery-powered applications.
