Inputs
  Input type                               Level-sensitive                                Level-sensitive
  High-level input voltage                 2.0V minimum                                   2.0V minimum
  Low-level input voltage                  0.8V maximum                                   0.8V maximum
  Minimum pulse width                      Not applicable                                 66ns high and low*
Outputs
  Output driver high voltage               2.4V minimum (IOH = -15mA)                     2.4V minimum (IOH = -15mA)
