NOTES:
1. At f = f MAX , address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/t CYC , using "AC TEST CONDITIONS" at input
levels of GND to 3V.
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. V DD = 3.3V, T A = 25°C for Typ, and are not production tested. I DD DC (f=0) = 120mA (Typ).
5. 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 DDQ - 0.2V
CE X > V DDQ - 0.2V means CE 0X > V DDQ - 0.2V or CE 1X < 0.2V
"X" represents "L" for left port or "R" for right port.
6. 166MHz Industrial Temperature not available in BF-208 package.
7. This speed grade available when V DDQ = 3.3.V for a specific port (i.e., OPTx = V IH ). This speed grade available in BC-256 package only.
