Working Principles

The 74ACTQ373SJX operates based on the principle of transparent latching. When the clock input (CLK) is active, the data inputs (D0-D7) are transferred to the corresponding data outputs (Q0-Q7). The latch remains transparent as long as the output enable (OE) signal is active. When the OE signal is inactive, the latch holds the last transferred data.
