Product Features:
MCP23017 can convert 16 bit parallel data into serial data on the IC interface and can convert each other. Internally integrated power on reset (POR) circuit, reset to the default state of the device. Two independent programmable interrupt source outputs. The polarity flip register can be configured with GPIO input polarity or output, and can be set to use pull-up resistors. The interrupt function can be activated for all 10 configured inputs. 10 ports have strong driving ability, and the current can be poured and pulled up to 25mA
