AAT4291 Features
* a 500ns turn-on time. The switch states are controlled by AnalogicTech’s Simple Serial Control™ (S2Cwire™) interface which permits ease of control and efficiency of size. The quiescent supply current is very low, typically 5µA. In shutdown mode, the supply current is reduced to less than 1µA. The AA
