Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied.

应用信息

整个供电电压范围内开关，且导通电阻变化极小 (见双向的，因此为输出。

电源旁路能够改善噪声容限，并能阻止开关噪声从V+电源传播到其他器件。在V+和容即可满足大多数应用的要求。
