AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage Range
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access RAM, CE = V
4. 'X' in part number indicates power rating (S or L).
