Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

1. The RqJA is highly dependent on the PCB heat sink area (connected to PAD1). See PCB recommendation paragraph.

ELECTRICAL CHARACTERISTICS Min / Max limits values (−40°C < TA < +85°C) and IN = +5 V (Unless otherwise noted). Typical

values are TA = +25°C
