MAX6816EUS+

The MAX6816EUS+ is an integrated circuit (IC) component that offers versatile keypad or switch debouncing functionality. It provides a simple and efficient way to implement capacitive-touch or push-button keypads in various applications ranging from consumer electronics to industrial control systems. One of the key features of the MAX6816EUS+ is its ability to debounce up to 16 push-button switches or capacitive-touch sensors. Debouncing is the process of removing the unwanted noise and fluctuations generated during the operation of mechanical switches or capacitive sensors. This ensures reliable and clean input signals, preventing false triggering and improving overall system performance. The IC operates with a wide supply voltage range, from 1.7V to 5.5V, making it compatible with a broad range of microcontrollers and other digital devices. It offers configurable inputs/outputs, allowing flexibility in configuring the keypad or switch matrix. Furthermore, the device offers programmable options, including the ability to assign individual switches as direct inputs or outputs, making it suitable for different keypad configurations. To simplify the integration process, the MAX6816EUS+ provides an I2C-compatible serial interface. This allows communication with the device using only two wires, reducing the overall complexity and minimizing the number of required input/output pins on the host microcontroller. The IC also supports a hardware interrupt output, allowing the microcontroller to be notified when a switch change is detected, reducing the need for continuous polling
