Note 1:
Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note 2:
This parameter is only sampled and is not 100% tested.
Note 3:
OE may be delayed up to t
ACC
–
t
OE
after the falling edge of CE without impacting t
ACC
.
Note 4:
The t
and t
compare level is determined as follows:
High to TRI-STATE, the measured V
OH1
(DC) - 0.10V;
Low to TRI-STATE, the measured V
OL1
(DC) + 0.10V.
Note 5:
TRI-STATE may be attained using OE or CE .
Note 6:
The power switching characteristics of EPROMs require careful device decoupling. It is recommended that at least a 0.1
μ
F ceramic capacitor be used on every device
between V
CC
and GND.
Note 7:
The outputs must be restricted to V
CC
+ 1.0V to avoid latch-up and device damage.
