Notes: 1. The max. output current may be as high as 20 mA, independent of the magnitude of V_CC, output short circuits to

V_CCcan cause excessive heating and eventual destruction.

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 becooming forward biased, acting as an input

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

comparators to go to the V_CCvoltage level (or ground if overdrive is large) during the time that an input is driven

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

when inputs become > ground or negative supply.

3. At output switch point, V _O= 1.4 Vdc, R_S= 100 Ω with V_CCfrom 5.0 Vdc to 30 Vdc, and over the full input

common mode range (0V to V_CC= –1.5V).

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.

5. Response time is specified with a 100mV step and 5.0mV of overdrive. For larger signals, 300ns is typical.

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.
