High-voltage level
High state must be present one setup time before the Low-to-High clock transition
Low-voltage level
Low state must be present one setup time before the Low-to-High clock transition
Lower case letters indicate the state of the referenced output prior to the Low-to-High clock transition
Don’t care
The output is High when CET is High and the counter is at terminal count (HHHH)
