Notes:
1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 0.9V/1.5V, input pulse levels of 0.4 to
Vdd-0.2V/0.4V to Vdd-0.3V and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured ±100 mV from steady-state voltage. Not 100% tested.
