H = HIGH voltage level
L = LOW voltage level
X = Don’t care
Z = High impedance “off” state
↑ = LOW-to-HIGH level transition
NOTES:
1. Output level before the indicated steady-state input conditions
were established, provided that CP is high before LE goes low.
2. Output level before the indicated steady-state input conditions
were established.
