NOTES:
5652 tbl 09
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".
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 = 2.5V, T A = 25°C for Typ, and are not production tested. I DD DC (f=0) = 15mA (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. 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 .
7. 166MHz I-Temp is not available in the BF-208 package.
8. 200Mhz is not available in the BF-208 package.
