NOTES:
1. At f = f MAX , address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/t RC , using "AC TEST CONDITIONS".
2. f = 0 means no address or control lines change. Applies only to input at CMOS level standby.
3. V DD = 2.5V, T A = 25°C for Typ. values, and are not production tested. I DD DC (f=0) = 100mA (Typ).
4. CE X = V IL means CE 0X = V IL and CE 1X = V IH
CE X = V IH means CE 0X = V IH or CE 1X = V IL
CE X < 0.2V means CE 0X < 0.2V and CE 1X > V DDQX - 0.2V
CE X > V DDQX - 0.2V means CE 0X > V DDQX - 0.2V or CE 1X - 0.2V
"X" represents "L" for left port or "R" for right port.
5. I SB1 , I SB2 and I SB4 will all reach full standby levels (I SB3 ) on the appropriate port(s) if ZZ L and /or ZZ R = V IH .
