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+.
