Working Principles

The 74AHCT273BQ-Q100X operates based on positive-edge triggering. When the clock pulse (CP) transitions from low to high, the data inputs (D0-D7) are latched into their corresponding flip-flops. The stored data can then be read from the output pins (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state. The master reset (MR) pin resets all flip-flops to a known state when activated.
