Description

The MCP23S17-E/SS I/O Expander is a versatile and reliable solution for expanding the number of I/O ports available on a system. It is designed to be used with a 10MHz SPI interface, and it is available in a 28-SSOP tube alternate packaging. This makes it easy to integrate into a variety of applications. With 16-bit I/O port expansion, the MCP23S17-E/SS I/O Expander can provide up to 16 additional I/O ports. Each I/O pin comes with an internal pull-up resistor, which allows for easy connection to external components. Additionally, the device includes an interrupt output pin that can alert the system when an input pin has changed state. The device is capable of operating in temperatures ranging from -40°C to 125°C, making it an ideal solution for industrial automation, home automation, and consumer electronics.
