H = HIGH voltage level;
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH clock transition;
L = LOW voltage level;
l = LOW voltage level one set-up time prior to the LOW-to-HIGH clock transition;
X = don’t care;
q = lower case letter indicates the state of the referenced input one set-up time prior to the LOW-to-HIGH transition.
The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
For SO14 packages: above 70 C the value of P
For TSSOP14 packages: above 60 C the value of P
For DHVQFN14 packages: above 60 C the value of P
= LOW-to-HIGH transition;
