FUNCTIONAL DESCRIPTION The CAT9555 general purpose input/output (GPIO) peripheral provides up to sixteen I/O ports, controlled through an I²C compatible serial interface The CAT9555 supports the I²C Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol defines any device that ...
