6.1 Absolute Maximum Ratings

Over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Supply voltage, V+ Pins 1, 20 26 V
Signal input pins Voltage(2) Pins 7, 8, 9, 12 –0.4 (V+) + 0.4 V
Pins 11, 15 –0.4 3.3
Current(2) Pins 7, 8, 9, 11, 12, 15 ±10 mA
Signal output terminals Voltage Pins 18, 19 –0.4 (V+) + 0.4 V
Pins 13, 14 –0.4 3.3

(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) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.4 V beyond the supply rails should be current limited to 10 mA or less.
(3) The device automatically goes into shutdown above +140℃ junction temperature
