over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC Supply voltage(2) 0 36 V VID Differential input voltage(3) –36 36 V VI Input voltage range (either input) –0.3 36 V VO Output voltage 0 36 V IO Output current 0 20 mA Duration of output short-circuit to ground(4) Unlimited IIK Input current(5) –50 mA TJ Operating virtual junction temperature –40 150 °C Tstg Storage temperature –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values, except differential voltages, are with respect to the network ground. (3) Differential voltages are at IN+ with respect to IN–. (4) Short circuits from outputs to VCC can cause excessive heating and eventual destruction. (5) Input current flows thorough parasitic diode to ground and will turn on parasitic transistors that will increase ICC and may cause output to be incorrect. Normal operation resumes when input current is removed.
