Overview
The NXP PCA9575PW1,118 is a 16-bit I2C-bus and SMBus I/O expander, designed to provide additional I/O ports to a microcontroller or other I2C-bus/SMBus master. This component is part of the PCA9575 series and is housed in a 24-pin TSSOP package. It is particularly useful in applications where more I/O ports are needed without increasing the pin count of the microcontroller.
