                                                                                                  PCA9539RPW/Q900J is a 16bit I²C-bus and SMBus low power I/O port with interrupt and reset 24-pin CMOS device. It 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 I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. It consists of two 8-bit configuration (input or output selection), input, output, and polarity inversion (active HIGH or active LOW operation) registers. The system can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the read register can be inverted with the Polarity inversion register.

                                                                                                  • 16bit I²C-bus GPIO with interrupt and reset
