'X' in part numbers indicates power rating (S or L). 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.
