High-Speed 32K x 16 Dual-Port Static RAM Military, Industrial and Commercial Temperature Ranges
NOTES:
1. Port-to-port delay through RAMcells fromwriting port to reading port, refer to "Timng Waveformof Write with Port-to-Port Read and
BUSY
(M/

)".
2. To ensure that the earlier of the two ports wins.
3. t
BDD
is a calculated parameter and is the greater of 0, t

(actual).
4. To ensure that the write cycle is inhibited on port "B" during contention on port "A".
5. To ensure that a write cycle is completed on port "B" after contention on port "A".
6. 'X' in part numbers indicates power rating (S or L).
7. Industrial temperature: for other speeds, packages and powers contact your sales office.
