Working Principles

The 74AHCT574D,118 is a positive-edge triggered octal D-type flip-flop. It stores and transfers data based on the rising edge of the clock pulse input (CP). The data inputs (D0-D7) are latched into their respective flip-flops when the clock signal transitions from low to high. The stored data can be accessed through the corresponding output pins (Q0-Q7). The Output Enable (OE) pin allows the outputs to be disabled, effectively disconnecting them from the bus.

Detailed Application Field Plans

The 74AHCT574D,118 is commonly used in various digital systems where data storage and transfer are required. Some application fields include: 1. Microcontrollers and microprocessors 2. Data communication systems 3. Memory modules 4. Industrial automation 5. Automotive electronics
