Instructions for Using 74ACT574

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (2.0V to 5.5V).
   • Connect the GND pin to the ground.

2. Input Signals:

   • Connect the data inputs (D0-D7) to the desired logic levels.
   • Connect the clock input (CLK) to the clock signal.
   • Connect the output enable (OE) pin to control the output state (active low).

3. Output Signals:

   • The outputs (Q0-Q7) will follow the data inputs on the rising edge of the clock signal when OE is low.
   • When OE is high, the outputs are in a high-impedance state.

4. Timing Considerations:

   • Ensure that the setup and hold times are met to avoid metastability issues.
   • The propagation delay time should be considered when designing the timing of your circuit.

5. Handling and Storage:

   • Store the device in a dry environment within the specified storage temperature range.
   • Handle with care to avoid damage from electrostatic discharge (ESD).

6. Application Examples:

   • Use the 74ACT574 as a data latch or buffer in digital circuits.
   • It can be used in memory interfaces, data buses, and other applications requiring synchronized data transfer.

By following these parameters and instructions, you can effectively use the 74ACT574 D-type flip-flop in your digital circuits.
