8-bit I2C and SMBus I/O port with interrupt, 2-kbit EEPROM and 6 address pins

DESCRIPTION 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
