Working Principles
The 74LVC126AD,112 is a quad buffer with 3-state outputs. It operates as a non-inverting buffer, meaning the output signal follows the input signal. The 3-state outputs allow the IC to be connected to a common bus, where multiple devices can share the same communication line without interfering with each other.
When the Output Enable (OE) pin is low, the outputs are enabled and actively drive the connected circuit. When the OE pin is high, the outputs enter a high-impedance state, effectively disconnecting them from the circuit.
