Notes : 1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current
is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simulta-
neous short-circuit on all amplifiers.
2. The direction of the input current is out of the IC. This current is essentially constant, independent of the state
of the output so no loading change exists on the input lines.

4. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more
than 0.3V. The upper end of the common-mode voltage range is VCC+- 1.5V, but either or both inputs can go
to +32V without damage.
5. Due to the proximity of external components insure that coupling is not originating via stray capacitance be-
tween these external parts. This typically can be detected as this type of capacitance increases at higher fre-
quences.
6. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the
collector-base junction of the input PNP transistor becoming forward biased and thereby acting as input di-
odes clamps. In addition to this diode action, there is also NPN parasitic action on the IC chip. this transistor
action can cause the output voltages of the Op-amps to go to the VCC voltage level (or to ground for a large
overdrive) for the time duration than an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3V.
