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 overshoot to +7.0 volts for pulses of less than 20 ns.
Notes:
1. X can be V
IL
or V
IH
.
2. Refer to Programming Characteristics.
3. V
H
= 12.0
±
0.5V.
4. 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................................ -55°C to +125°C
*NOTICE:
Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to
the device. This is a stress rating only and func-
tional operation of the device at these or any other
conditions beyond those indicated in the opera-
tional sections of this specification is not implied.
Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Storage Temperature..................................... -65°C to +150°C
