Notes:
1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 1.5V, input pulse levels of
0 to 3.0V and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured
±
500 mV from steady-state voltage. Not 100% tested.
3. Not 100% tested.
