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
output loading specified in Figure 1a.
2. Tested with the load in Figure 1b. 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.
4. Tested with OE HIGH.
