High-Speed 16K x 8 Dual-Port Static RAM Military, Industrial and Commercial Temperature Ranges

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested but not tested.
3. To access RAM, CE = V
IL, SEM = VIH. To access semaphore, CE = VIH and SEM = VIL. Either condition must be valid for the entire tEW time.
4. The specification for t
DH 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 t
DH will always be smaller than the actual tOW.
5. 'X' in part numbers indicates power rating (S or L).
