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
Since CE input is sensitive to very short (<3ns) high-to-low-to-high going spikes while CP is high, users should avoid the use of decoders
or other potentially glitch prone device on the CE input.
