PCA9501 8-bit I2C and SMBus I/O port

The PCA9501 is an 8-bit I/O expander with an on-board 2-kbit EEPROM. The I/O expandable eight quasi-bidirectional data pins can be independently assigned as inputs or outputs to monitor board level status or activate indicator devices such as LEDs. The system master writes to the I/O configuration bi.
