Note 1. Voltage values are with respect to network GND terminal.
Note 2. This rating is valid for the condition that all pins are soldered into a printed circuit board with
a 2” x 2” copper layer area of 14 mil thickness. Most of the heat is conducted to the printed
circuit board copper layer through Pin8 (Input GND).
