NOTES:

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

2. VCC = 3.3V, TA = +25°C, and are not production tested. ICCDC = 80mA (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".
