MAX11042 Datasheet | Maxim Integrated

19-3984; Rev 1; 8/07 .. Wired Remote Controllers General Description The MAX11041/MAX11042 wired remote controllers convert up to six or 30 different pushbuttons into an I2C register. Together with low-cost pushbutton switches and 1% resistors, the MAX11041/MAX11042 are total solutions over a single-wire interface. A wired remote controller easily piggybacks to a standard 3.5mm headphone jack using a fourth contact or one of the audio signals. To conserve battery life, the MAX11041/MAX11042 consume only 5µA (typ) while reading keypresses in real time without microprocessor (µP) polling. The devices send the debounced keypress along with key duration to the application...
