Flip Flops FAQ

What is the logic polarity of the SN74HCT564N outputs?

The outputs are inverting, meaning the Q output is the logical complement of the D input state at the time of the clock edge.

Does the SN74HCT564N support bus-driven architectures?

Yes, the three-state output feature allows the device to be directly connected to bus lines, enabling multiple devices to share the same data path.
