Working Principles

The SN74ACT564DBRG4 is an octal D-type flip-flop IC that stores and transfers digital data. It operates on the rising edge of the clock pulse input (CP), capturing the data inputs (D0-D7) and storing them in the flip-flops. The stored data can then be accessed through the corresponding flip-flop outputs (Q0-Q7).

The output enable input (OE) controls the state of the flip-flop outputs. When OE is low, the outputs are enabled and reflect the stored data. Conversely, when OE is high, the outputs are disabled and enter a high-impedance state, allowing other devices to drive the shared bus.

Detailed Application Field Plans

The SN74ACT564DBRG4 is commonly used in various digital logic applications, including:

1. Microprocessors and microcontrollers
2. Data storage systems
3. Communication equipment
4. Industrial automation
5. Automotive electronics
6. Consumer electronics

Its high-speed operation and 3-state outputs make it suitable for applications requiring efficient data transfer and bus sharing.
