CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1.
θ
JA
is measured with the component mounted on an evaluation PC board in free air.
2. For supply voltages less than
±
15V, the absolute maximum input voltage is equal to the supply voltage.
3. Short circuit may be to ground or either supply. Rating applies to 70
o
C ambient temperature.
4. Input voltages may exceed the supply voltages provided the input current is limited to
±
100
μ
A.
5. Connecting any digital inputs or outputs to voltages greater than V+ or less than GND may cause destructive device latchup. For this
reason it is recommended that the power supply to the ICL7104 be established before any inputs from sources not on that supply are
applied.
