1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0V to
2. The internal write time is defined by the overlap of CE LOW and UB or LB, and WE LOW. All signals must be in valid states
3. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
