1. "X" in part numbers indicates power rating (S or L).
2. VCC = 5V, TA = +25°C and are not production tested. ICC DC = 120mA (typ.)
3. At f = fMAX, address and I/O'S 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 port opposite port "A".
