MCP23016-I/SP (MICROCHIP)

The MCP23016-I/SP is a 16-bit I?C™ I/O Expander provides 16-bit, general purpose, parallel I/O expansion for I?C™compatible bus applications. It includes high-current drive capability, low supply current and individual I/O configuration. I/O expander provides a simple solution when additional I/Os are needed for ACPI, power switches, sensors, push buttons, LEDs and so on. The MCP23016 consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master enables 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 read register can be inverted with the polarity inversion register. All registers can be read by the system master.
