Notes:
1. Test conditions assume signal transition times of 2 ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V
2. Tested with the load in Figure 2. Transition is measured ±200 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE1, CE2 LOW, CE2 HIGH and WE LOW. All signals must be in valid

referenced to the rising or falling edge of the signal that terminates the write.
