WRITE CYCLE SWITCHING CHARACTERISTICS
Notes:
1. Test conditions assume signal transition times of 3ns or less, timing reference levels of 1.5V, input pulse levels of 0 to 3.0V and
2. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
3. The internal write time is defined by the overlap of CE LOW and WE LOW. All signals must be in valid states to initiate a Write, but

any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of
the signal that terminates the Write.
