(1)
Output Compatible With TTL, MOS, and CMOSSingle Supply or Dual SuppliesWide Range of Supply Voltage Max Rating . . . 2 V to 36 V Tested to 30 V(1) Component qualification in accordance with JEDEC andindustry standards to ensure reliable operation over anextended temperature range. This includes, but is not limitedto, Highly Accelerated Stress Test (HAST) or biased 85/85,temperature cycle, autoclave or unbiased HAST,electromigration, bond intermetallic life, and mold-compoundlife. Such qualification testing should not be viewed asjustifying use of this component beyond specifiedperformance and environmental limits.
This device consist of two independent voltage comparators that are designed to operate from a single powersupply over a wide range of voltages. Operation from dual supplies also is possible as long as the differencebetween the two supplies is 2 V to 36 V, and V
CC
is at least 1.5 V more positive than the input common-modevoltage. Current drain is independent of the supply voltage. The outputs can be connected to otheropen-collector outputs to achieve wired-AND relationships.
The LM293-EP is characterized for operation from 55 °C to 125 °C.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratingsonly, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operatingconditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.(2) All voltage values, except differential voltages, are with respect to GND.(3) Differential voltages are at IN+, with respect to IN .(4) Short circuits from outputs to V

(1) Full range (MIN or MAX) for LM293 is 55 °C to 125 °C. All characteristics are measured with zero common-mode input voltage, unlessotherwise specified.(2) The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of thecommon-mode voltage range is V
CC+
1.5 V for the inverting input ( ), and the non-inverting input (+) can exceed the V
