Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse
levels of 0 to 3.0V and output loading specified in .igure 1.
2. Tested with the load in .igure 2. Transition is measured ±200 mV from steady-state voltage. Not 100%
tested.
3. Not 100% tested.
