Notes:
18. Input tR = tF = 2.0ns, 10% to 90% at VIN = 1.65V to 1.95V;
Input tR = tF = 2.0ns, 10% to 90% at VIN = 2.3 to 2.7V;
Input tR = tF = 2.5ns, 10% to 90%, at VIN = 3.0V to 3.6V only;
Input tR = tF = 2.5ns, 10% to 90%, at VIN = 4.5V to 5.5 only.
19. VCCI = VCCA for control pin OE or Vmi = (VCCA / 2).
