Working Principles

The CY74FCT377ATQCT is a D-type flip-flop with a transparent latch. It operates based on the clock signal provided at the CP pin. When the clock signal transitions from low to high, the data present at the D input is transferred to the Q output. The transparent latch feature allows continuous data transfer as long as the LE input is enabled. The MR input can be used to reset the flip-flop to a known state. The OE input controls the output enable/disable functionality.
