NOTES:
1. Address A 14X is a NC for IDT70V9269.
2. LB and UB are single buffered regardless of state of FT /PIPE.
3. CE 0 and CE 1 are single buffered when FT /PIPE = V IL ,
CE 0 and CE 1 are double buffered when FT /PIPE = V IH ,
i.e. the signals take two cycles to deselect.

LB and UB are single buffered regardless of state of FT /PIPE.
5. CE o and CE 1 are single buffered when FT /PIPE = V IL . CE o and CE 1 are double buffered when FT /PIPE = V IH , i.e. the signals take two cycles to deselect.
