Working Principles

The MC74VHCT126AMEL is a quad buffer with 3-state outputs. It operates by receiving digital input signals on the A inputs and amplifying them to the Y outputs. The OE (Output Enable) pin controls the output state, allowing the device to be enabled or disabled. When the OE pin is high, the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit.
