Working Principles

SN74LV273APW operates based on the principles of D-type flip-flops. It stores digital information at its inputs (D0-D7) and updates the stored values based on the rising edge of the clock signal (CLK). The asynchronous clear input (CLR) allows for resetting all flip-flops simultaneously. The outputs (Q0-Q7) reflect the stored values and can be used for further processing or driving external circuitry.
