PCA9539PWR Allgemeine Beschreibung

The PCA9539PWR is a versatile device that allows for easy reset and initialization by simply asserting a low in the RESET input. This feature is particularly useful in case of time-out or improper operation, ensuring that the registers are restored to their default state. The open-drain interrupt output (INT) signals any changes in input state to the system master, enabling quick and efficient communication without the need for continuous monitoring via the I2C bus
