AC TEST CONDITIONS
Input pulse levels ................................... Vss to 3.0V
Input rise and fall times ....................................... 3ns
Input timing reference levels ............................. 1.5V
Output reference levels ..................................... 1.5V
Output load ......................................... See Figures 1

NOTES
1. Overshoot: Vcc +3.0V for pulse width < 20ms.
2. Undershoot: -3V for pulse width < 20ms.
3. I is dependent on output loading and cycle rates.
CC
4. This parameter is guaranteed but not tested.
5. Test conditions as specified with the output loading
as shown in Fig. 1 unless otherwise noted.
6. At any given temperature and voltage condition,
tHZCE is less than tLZCE, and tHZWE is less than
tLZWE.
7. WE\ is HIGH for READ cycle.
8. Device is continuously selected. Chip enables and
output enables are held in their active state.
9. Address valid prior to, or coincident with, latest
occurring chip enable.
10. tRC = Read Cycle Time.
11. Chip enable and write enable can initiate and
terminate a WRITE cycle.
12. Output enable (OE\) is inactive (HIGH).
13. Output enable (OE\) is active (LOW).
14. ASI does not warrant functionality nor reliability of
any product in which the junction temperature
exceeds 150°C. Care should be taken to limit power to
acceptable levels.
15. All voltage referenced to Vss (GND).
