Notes:
1.  Test conditions assume signal transition times of 1.5 ns or less, timing reference levels of 1.25V, input pulse levels of 0.4V to
Vdd-0.3V and output loading specified in Figure 1a.
2.  Tested with the load in Figure 1b. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3.  Not 100% tested.
