Working Principles

The 74VHC126PW-Q100J is a quad buffer/driver IC that operates by receiving input signals on the A and B pins. When the Output Enable (OE) pin is set to a logic high level, the input signals are buffered and amplified, and the resulting output is available on the Y pin. Conversely, when the OE pin is set to a logic low level, the outputs are disabled, and the Y pins are in a high-impedance state.
