1. General description
2. Features
3. Applications
The PCA8575 provides general purpose remote I/O expansion for most microcontroller
families via the two-line bidirectional I
The device consists of a 16-bit quasi-bidirectional port and an I
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.
