Note:
1.
Minimum voltage is -0.6V dc which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is
V
CC
+ 0.75V dc which may be exceeded if certain precautions are observed (consult application notes) and which may
overshoot to +7.0V for pulses of less than 20 ns.
Notes:
1. X can be V
IL
or V
IH
.
2. Read, output disable, and standby modes require, 2.7V
≤
V
CC
≤
3.6V, or 4.5V
≤
V
CC
≤
5.5V.
3. Refer to Programming Characteristics. Programming modes require V
CC
= 6.5V.
4. V
H
= 12.0
±
0.5V.
5. Two identifier bytes may be selected. All Ai inputs are held low (V
IL
), except A9 which is set to V
H
and A0 which is toggled low
(V
IL
) to select the Manufacturer’s Identification byte and high (V
IH
) to select the Device Code byte.
Absolute Maximum Ratings*
Temperature Under Bias.................................. -40°C to +85°C
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond 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
