The PCA9672 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
family.
The PCA9672 is a drop-in upgrade for the PCF8574 providing higher Fast-mode Plus
(Fm+) I2C-bus speeds (1 MHz versus 400 kHz) so that the output can support PWM
dimming of LEDs, higher I2C-bus drive (30 mA versus 3 mA) so that many more devices
can be on the bus without the need for bus buffers, higher total package sink capacity
(200 mA versus 100 mA) that supports having all LEDs on at the same time and more
device addresses (16 versus 8) are available to allow many more devices on the bus
without address conflicts.
