Working Principles

The 54FCT573ATDB operates based on the principle of transparent latching. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The latch remains transparent as long as the latch enable input is high. When the latch enable input goes low, the outputs retain their last state until the latch enable input goes high again.

The output enable (OE) input controls whether the outputs are active or in a high-impedance state. When the output enable input is low, the outputs are active and reflect the data inputs. When the output enable input is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
