The PCA9539; PCA9539R is a 24-pin CMOS device that provides 16 bits of General
Purpose parallel Input/Output (GPIO) expansion with interrupt and reset for
I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors
family of I2C-bus I/O expanders. I/O expanders provide a simple solution when additional
