Operating Ratings are conditions under which operation of the device is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics. Note 2: The human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. Note 3: V CC provides self bias for the internal gate drive and control circuits. Device thermal limitations limit external loading Note 4: Typical specifications represent the most likely parametric norm at 25°C operation. 5 www.national.com |
