(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensured specific performance limits. For ensured specifications and test conditions, see, the

Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may

degrade when the device is not operated under the listed test conditions.

(2) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode

range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3 V

(or 0.3 V

below

the magnitude of the negative power supply, if used) (at 25°C).

(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 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 to 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 −0.3 V

(at

25°)C.

(4) The low bias dissipation and the ON-OFF characteristics of the outputs keeps the chip dissipation very small (P

≤ 100mW), provided

the output transistors are allowed to saturate.

(5) The maximum power dissipation must be derated at elevated temperatures and is dictated by T

Jmax

(maximum junction temperature),

(Package junction to ambient thermal resistance), and T

(ambient temperature). The maximum allowable power dissipation at any

temperature is P

Dmax

(7) Short circuits from the output to V

can cause excessive heating and eventual destruction. When considering short circuits to ground,

the maximum output current is approximately 20 mA independent of the magnitude of V
