Flip Flops FAQ

What is the output polarity of the SN74AC564DW?

The outputs are inverting, meaning the Q output reflects the complement of the D input state upon clock triggering.

Does the SN74AC564DW support through-hole mounting?

No, the DW suffix indicates a SOIC-20 surface-mount package designed for SMD/SMT installation.
