Working Principles

The SN74BCT574DW operates based on the principles of digital logic. It uses positive-edge-triggered D-type flip-flops to store and transfer data. When a clock pulse is applied to the CP pin, the data present at the D0-D7 inputs is latched and stored in the corresponding flip-flops. The stored data can then be accessed from the Q0-Q7 outputs. The OE (Output Enable) pin controls the output state of the flip-flops.
