PCA9671, Remote 16-bit I/O expander
The 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.
The PCA9671 is a drop in upgrade for the PCF8575 providing higher I2C-bus speeds (1 MHz versus 400 kHz) so that t
