Note 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

guarantee specific performance limits. For guaranteed specifications and test

conditions, see the Electrical Characteristics. The guaranteed specifications apply

only for the test conditions listed. Some performance characteristics may degrade

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

Note 2:

The maximum power dissipation must be derated at elevated temperatures and is

dictated by Tjmax (maximum junction temperature ), ThetaJA (package junction to

ambient thermal resistance), and TA (ambient temperature). The maximum allowable

power dissipation at any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number

given in the Absolute Maximum Ratings, whichever is lower.

Note 3:

The LM193A must be derated based on a 150 C maximum junction temperature. The low

bias dissipation and the ON-OFF characteristic of the outputs keeps the chip

dissipation very small (PD<100mV), provided the output transistors are allowed to

saturate.

Note 4:

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 20mA independent of the magnitude of V+.
