Working Principles

The 74AHCT126BQ,115 is a quad buffer with 3-state outputs. It operates as a logic gate that takes four independent input signals and buffers them to the corresponding output pins. The Schmitt-trigger action on all inputs ensures noise immunity by providing hysteresis.

The output enable (OE) pin controls the 3-state outputs. When OE is low, the outputs are enabled and reflect the input signals. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus lines.
