Working Principles

MC74AC573NG operates as an octal transparent latch with 3-state outputs. The latch enable (LE) input controls the latching of data from the data inputs (D0-D7) to the outputs (Q0-Q7). The output enable (OE) input determines whether the outputs are active or in a high-impedance state.

When LE is high, the latch is enabled, allowing the data inputs to propagate to the outputs. When OE is low, the outputs are active and reflect the current state of the latch. Conversely, when OE is high, the outputs enter a high-impedance state, disconnecting them from the rest of the circuit.
