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. 1 2 3 4 8 7 6 5 VCC 2OUT 2IN– 2IN+ 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.

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.

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.
