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
No change
Don’t care
High impedance “off” state
Low-to-High clock transition
Not Low-to-High clock transition
ABSOLUTE MAXIMUM RATINGS
(Operation beyond the limit set forth in this table may impair the useful life of the device.
