PCA6416A
Product data sheet
INT can be connected to the interrupt input of a 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
remain a simple slave device.
The device Port P outputs have 25 mA sink capabilities for directly driving LEDs while
consuming low device current.
One hardware pin (ADDR) can be used to program and vary the fixed I
and allow up to two devices to share the same I
