High-Speed 8K x 9 Dual-Port Static RAM
Military, Industrial and Commercial Temperature Ranges

APRIL 04, 2006
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 not tested.
3. To access RAM,
CE = VIL and SEM = VIH. To access semaphore, CE = VIH and SEM = VIL. Either condition must be valid for the entire tEW time.
4. The specification for tDH must be met by the device supplying write data to the RAM under all operating conditions. Although tDH and tOW values will vary over voltage
and temperature, the actual tDH will always be smaller than the actual tOW.
5. 'X' in part numbers indicates power rating (S or L).
