H = High voltage level

L = Low voltage level

X = Don’t care

↑ = Low-to-High Clock transition

h = High voltage level one set-up time prior to the Low-to-High Clock transition.

l = Low voltage level one set-up 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.)
