WRITE CYCLE SWITCHING CHARACTERISTICS
Notes:
1. Test conditions assume signal transition times of 3 ns or less, timing reference levels of 1.5V, input pulse levels of
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 UB or LB and WE LOW. All signals must be in
8
Notes:
1. WE is HIGH for a Read Cycle.
2. The device is continuously selected. OE, CE, UB, or LB = V
3. Address is valid prior to or coincident with CE LOW transition.
