... The AAT4296/98 operates over an input voltage range of 1.8V to 5.5V, making it ideal for battery-powered appli- cations. The state of each output channel is controlled with a single GPIO via the EN/SET pin using AnalogicTech’s Simple Serial Control™ (S Cwire™) interface. When EN/ 2 SET is pulled to logic high, the device is enabled and consumes 3μ ...
