... PCA8575 has a low current consumption and includes latched outputs with high current drive capability for directly driving LEDs. The PCA8575 also possesses an interrupt line (INT) which can be connected to the interrupt logic of the microcontroller. By sending an interrupt signal on this line, the remote I/O can inform the microcontroller if there is incoming data on its ports without having to communicate via the I inputs ...

... PCA8575 acknowledges and the master sends the first data byte for P07 to P00. After the first data byte is acknowledged by the PCA8575, the second data byte P17 to P10 is sent by the master. Once again, the PCA8575 acknowledges the receipt of the data. Each 8-bit data is presented on the port lines after it has been acknowledged by the PCA8575 ...

... PCA8575 registers and I states. Thereafter V 8.5 Interrupt output (INT) The PCA8575 provides an open-drain interrupt (INT) which can be fed to a corresponding input of the microcontroller (see chips a kind of master function which can initiate an action elsewhere in the system. An interrupt is generated by any rising or falling edge of the port inputs. After time t signal INT is valid ...

... NXP Semiconductors 10.3 Differences between the PCA8575 and the PCF8575 The PCA8575 is a drop in replacement for the PCF8575 and can used without electrical or software modifications, but there is a difference in interrupt output release timing during the read operation. Write operations are identical. At the completion of each 8-bit write sequence the data is stored in its associated 8-bit write register at ACK or NACK. The fi ...
