7. At any given temperature and voltage condition,
tHZCE is less than tLZCE, and tHZWE is less than tLZWE
8. WE\ is HIGH for READ cycle.
NOTES
.
1. All voltages referenced to VSS (GND).
2. -3V for pulse width < 20ns
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. RC = Read Cycle Time.
12. CE2 timing is the same as CE1\ timing. The waveform
is inverted.
3. ICC is dependent on output loading and cycle rates.
The specified value applies with the outputs
unloaded, and f =
1
Hz.

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. 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.
