Working Principles

The SN74AHC125PWRE4 is a quad bus buffer gate with 3-state outputs. It operates as a non-inverting buffer/driver, meaning the output signal follows the input signal. The 3-state outputs allow the device to disconnect from the bus, effectively isolating it from other devices on the same bus.

When the Output Enable (OE) pin is low, the outputs (Y1-Y4) are active and mirror the inputs (A1-A4, B1-B2). When OE is high, the outputs enter a high-impedance state, effectively disconnecting them from the bus.
