Working Principles

DM74125N operates by receiving input signals at the A1, A2, A3, and A4 pins. These signals are then buffered and amplified internally. The tri-state outputs (Y1, Y2, Y3, and Y4) can be enabled or disabled using the OE pin. When the OE pin is high, the outputs are active and reflect the input signals. Conversely, when the OE pin is low, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
