Electrical Characteristics (Continues)

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

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

an input clamp diode. There is also a lateral PNP parasitic transistor action which can cause the output voltage of

driven negative. This will not destroy the device when limited to the max rating and normal output states will

recover when the inputs become

≥ground or negative supply.

Note 4. The bias current flows out of the inputs due to the PNP input stage. This current is virtually constant,

independent of the output state.

Note 5. The response time specified is for a 100mV input step with 5mV overdrive For larger signals, 300ns is typical.

Note 6. Positive excursions of input voltage may exceed the power supply level. As long as one of the inputs remain

within the common-mode range, the comparator will provide the proper output state.

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

minus supply.
