1. 'X' in part number indicates power rating (S or L)
2. V CC = 5V, T A = +25°C, and are not production tested. I CC DC = 120mA (TYP.)
3. At f = f MAX , address and I/O' S 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".
