NOTES:

1. 'X' in part numbers indicates power rating (SA or LA).
2. 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.
3. f = 0 means no address or control lines change. Applies only to inputs at CMOS level standby.
4. Vcc = 5V, T A =+25°C for Typ and is not production tested. Vcc DC = 100mA (Typ)
5. Port "A" may be either left or right port. Port "B" is opposite from port "A".
