NOTES:
1. Transition is measured
±
500mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. The specification for t
DH
must be met by the device supplying write data to the RAM under all operating conditions. Although t
DH
and t
OW
values will vary
over voltage and temperature, the actual t
DH
will always be smaller than the actual t
OW
.
4. Port-to-port delay through RAM cells from writing port to reading port, refer to “Timing Waveform of Write with Port-to-Port Read”.
5. (Commercial only), 0
°
C to +70
°

6. “X” in part number indicates power rating (SA or LA).

3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
NOTES:
1. Write cycle parameters should be adhered to, in order to ensure proper writing.
