DC Electrical Characteristics Over the Operating

Temperature and Supply Voltage Range (3) (VDD = 2.5V ± 100mV)

NOTES:

1. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/tCYC, using "AC TEST CONDITIONS".

2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.

3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".

4. VDD = 2.5V, TA = 25°C for Typ, and are not production tested. IDD DC(f=0) = 30mA (Typ).

5. CEX = VIL means CE0X = VIL and CE1X = VIH (enabled)

CEX

= VIH means CE0X = VIH and CE1X = VIL (disabled)

CEX

< 0.2V means CE0X < 0.2V and CE1X > VDDQ - 0.2V (enabled - CMOS levels)

CEX

> VDDQ - 0.2V means CE0X > VDDQ - 0.2V and CE1X < 0.2V (disabled - CMOS levels)

"X" represents "L" for left port or "R" for right port.

6. ISB1, ISB2 and ISB4 will all reach full standby levels (ISB3) on the appropriate port(s) if ZZL and/or ZZR = VIH.
