NOTES:
1. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency read cycle of 1/tRC, using "AC TEST CONDITIONS".
2. f = 0 means no address or control lines change. Applies only to input at CMOS level standby.
3. VDD = 2.5V, TA = 25°C for Typ. values, and are not production tested. IDD DC(f=0) = 100mA (Typ).
4. CEX = VIL means CE0X = VIL and CE1X = VIH
CEX = VIH means CE0X = VIH or CE1X = VIL
CEX < 0.2V means CE0X < 0.2V and CE1X > VDDQX - 0.2V
CEX > VDDQX - 0.2V means CE0X > VDDQX - 0.2V or CE1X - 0.2V
"X" represents "L" for left port or "R" for right port.
5. ISB1, ISB2 and ISB4 will all reach full standby levels (ISB3) on the appropriate port(s) if ZZL and /or ZZR = VIH.
6. 8ns Commercial and 10ns Industrial speed grades are available in BF-208 and BC-256 packages only.
