Electrical Characteristics (Continues)

Note 2. This magnitude of input current will only occur if the input leads are driven more negative than ground or the

negative supply voltage. This is due to the input PNP collector base junction becoming forward biased acting as

an input clamp diode. There is also a lateral PNP parasitic transistor action on the IC chip. This phenomena can

the time the input is driven negative. This will not destroy the device and normal output states will recover when

the inputs become -0.3V of ground or negative supply.

Note 4. Due to the PNP transistor inputs, bias current will flow out of the inputs, this current is essentially constant

independent of the output state, therefore, no loading changes will exist on the input lines.

Note 5. Input common mode of either input should not be permitted to go more than 0.3V negative of ground or minus

30volts without damage.

Note 6. Response time is specified with a 100mV step and 5.0mV of overdrive. With larger magnitudes of overdrive

faster response times are obtainable.

must remain within the common mode range. The low input state must not be less than -0.3volts of ground of

minus supply.
