6.1 Absolute Maximum Ratings

At TJ = 25°C, unless otherwise noted. All voltages are with respect to GND.(1)
MIN MAX UNIT
Voltage Input range, VIN –0.3 6 V
Enable range, VEN –0.3 VIN + 0.3
Output range, VOUT –0.3 6
Current Maximum output, IOUT Internally limited
Output short-circuit duration Indefinite
Continuous total power dissipation, PDISS See Thermal Information
Temperature Junction, TJ –55 150 °C
Storage junction, Tstg –55 150
(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.

6.2 ESD Ratings

VALUE UNIT
