PCA9558PW: 8-bit I²C-bus and SMBus I/O port
The PCA9558 is a highly integrated, multi-function device that is composed of a 5-bit
multiplexed/1-bit latched 6-bit I²C-bus/SMBus EEPROM DIP switch, an 8-bit I/O expander
and a 2-kbit serial EEPROM with write protect. The PCA9558 integrates these commonly
used components into a single chip to reduce component count and board space
requirements and is useful in computer, server and telecom/networking applications.
The PCA9558 has one address pin, allowing up to two devices to be placed on the same
I²C-bus or SMBus.
