NOTES:
1. 'X' in part number indicates power rating (S or L)
2. V
CC
= 3.3V, T
A
= +25°C, and are not production tested. I
CCDC
= 80mA (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".
