Up to 8 PCF8574 IO Expansion Boards can be connected to the I2C bus in parallel. That provide to add to your development system additional 64 I/O ports. Which controlled from single I2C bus. The PCF8574 IO Expansion Board features I2C pin header on one side. And I2C female connector on the opposite side, hence, it's more flexible to connect that board to your development system. That board also supports I2C cascading. Allowing multi boards connection to the I2C bus at the same time by connecting the pin header and a female connector. It is tiny dimensions and light weight allow easily to build it in as module to any board or whole system. That module can be used by programmers. Hardware engineers, scientifics, LAB technicians, firmware engineers etc. Technical specifications: Supply voltage range 2.5V- 6V Supply current consumption 100uA max. SCL. SDA input capacitance 7pF IO output current up to 25mA SCL frequency up to 100kHZ I2C address range 40h- 4Eh(8 different addresses supported) Open drain interrupt output Supported You can find more detailed datasheet at follow link: Highlights: PCF8574 is 8-bit bi-directional input output parallel port with I2C interface. Open drain multi purpose interrupt signal supported· 3 address bits enable to cascade on one I2C bus. Up to 8 expansion boards. 3 included jumpers enable switching an expansion board I2C address to any from 8 I2C addresses.
