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

The PCA9501 is an 8-bit I/O expander with an on-board 2-kbit EEPROM.\nThe 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 8 general purpose input/output expander/collector\nReplacement for PCF8574 with integrated 2-kbit EEPROM\nInternal 256 x 8 EEPROM\nSelf timed write cycle (5 ms typical)\n16 byte page write operation\nI2C-bus and SMBus interface logic\nInternal power-on reset\nNoise filter on SCL/SDA inputs\nActive L;
