AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage
(5)
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage from the Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization but not production tested.
3. For MASTER/SLAVE combination, t
WC = tBAA + tWR + tWP, since R/W = VIL must occur after tBAA.
4. The specification for tDH must be met by the device supplying write data to the RAM under all operation conditions. Although tDH and tOW values will vary over voltage
and temperature, the actual t
DH will always be smaller than the actual tOW.
5. 'X' in part number indicates power rating (SA or LA).
