1. H = HIGH Voltage Level
L = LOW Voltage Level
X = Don't Care
Z = High-Impedance
↑ = LOW-to-HIGH Transition
2. Output level before the indicated steady-state
input conditions were established, provided that
CLK is HIGH before LE went LOW.
3. Output level before the indicated steady-state
input conditions were established.
