NOTES:
2911 tbl 09b
1. 'X' in part number indicates power rating (S or L)
2. VCC = 3.3V, TA = +25°C, and are not production tested. ICC DC = 115mA (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".
