Working Principles

The N74F543DB,112 is an octal D-type flip-flop with 3-state outputs. It operates based on the positive edge-triggered principle, where the input data is latched into the flip-flops on the rising edge of the clock pulse. The output state can be enabled or disabled using the output enable (OE) pin. When the OE pin is high, the outputs are active, and when it is low, the outputs are in a high-impedance state.

The master reset (MR) pin allows for simultaneous clearing of all flip-flops, setting their outputs to a known state. This feature is useful during initialization or error recovery.
