ACTEST 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 V
SS (GND).
2.
-2V for pulse width < 20ns
3.
I
CC 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.
tLZCE, tLZWE, tLZOE, tHZCE, tHZOE and tHZWE
are specified with CL = 5pF as in Fig. 2. Transition is
measured ±200mV typical from steady state voltage,
allowing for actual tester RC time constant.
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.
