Remote 16-bit I/O expander for Fm+ I2C-bus with reset

OverviewThe PCA9671 provides general purpose remote I/O expansion for most microcontroller families via the two-line bidirectional bus (I²C-bus) and is a part of the Fast-mode Plus (Fm+) family.\n The PCA9671 is a drop in upgrade for the PCF8575 providing higher I²C-bus speeds (1 MHz versus 400 kHz) \n•1 MHz I²C-bus interface\n•Compliant with the I²C-bus Fast-mode and Standard-mode\n•SDA with 30 mA sink capability for 4000 pF buses\n•2.3 V to 5.5 V operation with 5.5 V tolerant I/Os\n•16-bit remote I/O pins that default to inputs at power-up\n•Latched outputs with 25 mA sink capability for dire;
