Electrical Characteristics
limits in boldface type apply over the junction temperature (T
guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm, and are
provided for reference purposes only.
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings define the conditions under which the device
is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
