Note 1: All voltages are measured with respect to the GND pin (4), unless otherwise specified.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which

guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit

is given, however, the typical value is a good indication of device performance.

Note 3: For operating at case temperatures above 25˚C, the device must be derated based on a 150˚C maximum junction temperature and a thermal resistance

of

Note 4: Human body model, 100 pF discharged through a 1.5 k

Ω resistor.

Note 5: Typicals are measured at 25˚C and represent the parametric norm.

Note 6: Limits are guarantees that all parts are tested in production to meet the stated values.
