AC TEST CONDITIONS
Input pulse levels ................................... Vss to 3.0V
Input rise and fall times ....................................... 5ns
Input timing reference levels ............................. 1.5V
Output reference levels ..................................... 1.5V
Output load .............................. See Figures 1 and 2
NOTES
1. All voltages referenced to VSS (GND).
2. -3V for pulse width < 20ns
3. ICC is dependent on output loading and cycle rates.
The specified value applies with the outputs
unloaded, and f = 1 Hz.
tRC (MIN)
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. Minimum of 5pF for tEHQZ, tOHQZ, tELQX, tOLQX,
and tWHQX.

7. At any given temperature and voltage condition,
tHZCE is less than tLZCE, and tHZWE is less than
tLZWE and tHZOE is less than tLZOE.
8. WE\ is HIGH for READ cycle.
9. Device is continuously selected. Chip enables and
output enables are held in their active state.
10. Address valid prior to, or coincident with, latest
occurring chip enable.
11. tRC = Read Cycle Time.
12. Chip enable (CE\) and write enable (WE\) can initiate and
terminate a WRITE cycle.
