MICROCIRCUIT DATA SHEET
(Continued)
Note 6:
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 diode clamps. In
addition to this diode action, there is also lateral NPN parasitic transistor action
on the IC chip. This transistor action can cause the output voltages of the
comparators to go to the V+ voltage level (or 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 -0.3Vdc.
Human body model, 1.5K Ohms in series with 100pF.
