NOTES:
3242 tbl 09
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" 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. Vcc = 5V, TA = 25°C for Typ, and are not production tested. ICC DC(f=0) = 150mA (Typ).
5. 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 > VCC - 0.2V
CEX > VCC - 0.2V means CE0X > VCC - 0.2V or CE1X < 0.2V
"X" represents "L" for left port or "R" for right port.
6. 'X' in part numbers indicate power (S or L).
7. Industrial temperature: for specific speeds, packages and powers contact your sales office.
