WRITE CYCLE SWITCHING CHARACTERISTICS
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
2. The internal write time is defined by the overlap of CE1 LOW, CE2 HIGH and WE LOW. All signals must be in valid states to
3. Tested with OE HIGH.
4. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
