    16-Bit, Open Drain I/O Expander with 12C Interface

     

    产品信息

    The MCP23X18 device provides 16-bit, general purpose parallel I/O expansion for I2C bus or SPI applications. The two devices differ only in the serial interface.
    • MCP23018 - I2C interface
    • MCP23S18 - SPI interface
    The MCP23X18 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing 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 input port register can be inverted with the polarity inversion register. All registers can be read by the system master.

     

      16-bit remote bidirectional I/O port

      Open-drain outputs:

      5.5V tolerant

      25 mA sink

      400 mA total current out

      Low standby current as low as 1 µA

      High-speed I2C™ interface up to 3.4MHz

      Single hardware address pin: Voltage input to allow up to eight devices on the bus

      Configurable interrupt output pins: Configurable as active-high, active-low or open-drain

      Low standby current:1 µA (typ.)
