The device consists of a 16-bit quasi-bidirectional port and an I2C-bus interface. The PCF8575C has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. It also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller.

overwritten. When the PCF8575C receives the pairs of data bytes, the first byte is referred to as P07– P00 and the second byte as P17– P10. The third byte is referred to as P07– P00, the fourth byte as P17– P10, and so on. Before reading from the PCF8575C, all ports desired as input should be set to logic 1. To read from the ports
In the event of a glitch or data corruption, PCF8575C can be reset to its default conditions by using the power-on. reset feature. Power-on reset requires that the device go through a power cycle to be completely reset. This. reset also happens when the device is powered on for the first time in an application.
