NOTES:
1. 'X' in part numbers indicates power rating (S or L).
2. VCC = 3.3V, TA = +25°C, and are not production tested. ICCDC = 70mA (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. Applies only to inputs at CMOS level standby.
5. Port "A" may be either left or right port. Port "B" is opposite from port "A".
