NOTES:
1. 'X' in part numbers indicates power rating (S or L)
3740 tbl 10b
2. VDD = 3.3V, TA = +25°C, and are not production tested. IDD DC = 90mA (Typ.)
3. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, and using “AC Test Conditions" of input levels of GND
to 3V.
4. f = 0 means no address or control lines change.
5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
6. Refer to Chip Enable Truth Table.
