3 / 40 page www.ti.com ABSOLUTE MAXIMUM RATINGS DISSIPATION RATINGS TPS70745, TPS70748 TPS70751, TPS70758 TPS70702 SLVS291D – MAY 2000 – REVISED DECEMBER 2007 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltages are tied to network ground.
