Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold-compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION
This device consist of two independent voltage comparators that are designed to operate from a single power
supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference
between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode
voltage. Current drain is independent of the supply voltage. The outputs can be connected to other
open-collector outputs to achieve wired-AND relationships.
The LM293-EP is characterized for operation from –55°C to 125°C.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values, except differential voltages, are with respect to GND.
Differential voltages are at IN+, with respect to IN–.
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.

Full range (MIN or MAX) for LM293 is –55°C to 125°C. All characteristics are measured with zero common-mode input voltage, unless
otherwise specified.
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 the
common-mode voltage range is VCC+ – 1.5 V for the inverting input (–), and the non-inverting input (+) can exceed the VCC level; the
comparator provides a proper output state. Either or both inputs can go to 30 V without damage.
