Working Principles

The CD74FCT273M is a D-type flip-flop that stores a single bit of data. It operates based on the rising edge of the clock signal. When the clock enable (CE) input is high, the flip-flop is enabled, and the data on the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The clear (CLR) input, when activated, resets the flip-flop to a known state.
