Flip Flops FAQ

What is the logic polarity of the SN74ACT564DBRG4 outputs?

The outputs are non-inverting, meaning the Q output follows the D input state upon clock activation.

Does this device include an asynchronous reset function?

No, the SN74ACT564 does not feature an explicit reset pin; it relies on clock-edge triggering for data capture.
