(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
(2) All voltages are measured with respect to the ground pin, unless otherwise specified.
(3) Typical specifications are specified at +25OC and represent the most likely parametric norm.
(4) Datasheet max/min specification limits are ensured by design, test, or statistical analysis.
