Working Principles

The SN74AC574DWG4 is an octal D-type flip-flop that operates on positive-edge triggered clock signals. When the clock pulse rises, the inputs (D0-D7) are latched and stored in their respective flip-flops. The outputs (Q0-Q7) reflect the stored values and remain stable until the next clock pulse arrives.

The Master Reset (MR) input allows for clearing all flip-flops to a low state when activated. The Output Enable (OE) input can be used to disable the outputs, preventing any changes in the stored values.

Detailed Application Field Plans

The SN74AC574DWG4 is commonly used in various digital systems and applications, including:

  1. Microprocessors and microcontrollers
