on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V
+
voltage level (or to ground for a large overdrive) for the time duration
that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns to a value
greater than −0.3V (at 25˚C).

Note 9:
The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so
no loading change exists on the input lines.
Note 10:
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at 25˚C). The upper end of the
common-mode voltage range is V
+
− 1.5V (at 25˚C), but either or both inputs can go to +32V without damage (+26V for LM2902), independent of the magnitude
of V
+
.
Note 11:
Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be
detected as this type of capacitance increases at higher frequencies.
Note 12:
Refer to RETS124AX for LM124A military specifications and refer to RETS124X for LM124 military specifications.
Note 13:
