Working Principles

The 74HC541D,653 operates by receiving digital input signals on its A1 to A8 pins. These input signals are then buffered and amplified by the internal circuitry. The output signals, Y1 to Y8, can be enabled or disabled using the OE pin. When the OE pin is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. When the OE pin is low, the outputs mirror the input signals.
