8-bit I2C and SMBus I/O port with 2-kbit EEPROM

DESCRIPTION The PCA9500 is an 8-bit I/O expander with an on-board 2-kbit EEPROM. The I/O expander’s 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
