Notes to function table
1. H =
High–voltage level
2. h
=
High voltage level one setup time before the low–to–high clock transition
3. L
=
Low–voltage level
4. l
=
Low voltage level one setup time before the low–to–high clock transition
5. qn =
Lower case letters indicate the state of the referenced input (or output) one setup time prior to the low–to–high clock transition
6. X =
Don’t care
7.
