2. Short-circuits from the output to VCC+ can cause excessive heating and eventual destruction. The maximum output current is approximately

40mA, independent of the magnitude of VCC. At values of supply voltage in excess of +15VDC continuous short-circuits can exceed the

power dissipation ratings and cause eventual destruction.

3. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the

input PNP transistors becoming forward biased and thereby acting as input bias clamps. In addition, there is also lateral NPN parasitic

transistor action on the IC chip. This action can cause the output voltages of the op amps to go to the V+ rail (or to ground for a large

overdrive) during the time that the input is driven negative.
