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. Unless otherwise noted these limits are over the
operating free air temperature range.)
