Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of 0V
to 3.0V and output loading specified in Figure 1.
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 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.
3. Tested with the load in Figure 2. Transition is measured ±500 mV from steady-state voltage. Not 100% tested.
