Working Principles

SN74AHCT125QDRG4Q1 operates by receiving input signals on the A1, A2, A3, and B1, B2, B3 pins. These signals are buffered and amplified by the internal circuitry. The 3-state outputs (Y1, Y2, Y3, Y4) can be enabled or disabled using the GND pin. When enabled, the outputs reflect the input signals, allowing data transfer. When disabled, the outputs are in a high-impedance state, isolating the device from the bus.
