1. 'X' in part numbers indicates power rating (S or L)
2. V CC = 5V, T A = +25°C, and are not production tested. I CCDC = 120mA (Typ.)
3. At f = f MAX , address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/t RC, 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".
