NOTES:
H = High-voltage level
h = HIGH state must be present one set-up time before the HIGH-to-LOW enable transition
L = Low-voltage level
l = LOW state must be present one set-up time before the HIGH-to-LOW enable transition
NC= No change
X = Don’t care
Z = High impedance “off” state
↓ = HIGH-to-LOW enable transition
