H = High voltage level
h = High voltage level one setup time prior to Low-to-High clock transition
L = Low voltage level
l = Low voltage level one setup time prior to Low-to-High clock transition
X = Don’t care
↑
= Low-to-High clock transition
dn(qn) = Lower case letters indicate the state of the referenced input (or output) one setup time prior to the Low-to-High clock transition.
ABSOLUTE MAXIMUM RATINGS
(Operation beyond the limits set forth in this table may impair the useful life of the device.
Unless otherwise noted these limits are over the operating free-air temperature range.)
