Notes:

1. Test conditions assume signal transition times of 5 ns or less, input pulse levels of 0.4V to 1.4V and output loading specified in

Figure 1.

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.
