ABSOLUTE MAXIMUM RATINGS(1)
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
Supply Voltage, V+ to V–................................................................... 7.0V
Output Short-Circuit(2) .............................................................. Continuous
Operating Temperature ..................................................–40°C to +125°C
Storage Temperature .....................................................–65°C to +150°C
Junction Temperature .................................................................... +150°C
Lead Temperature (soldering, 10s)............................................... +300°C
NOTES: (1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods may degrade
device reliability. These are stress ratings only, and functional operation of the
device at these, or any other conditions beyond those specified, is not implied.
(2) Short circuit to ground.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
