2 / 63 page  NXP Semiconductors PCAL9722 Ultra low-voltage translating 22-bit SPI I/O expander with Agile I/O features, interrupt output and reset input pin state and keeps the logic values that created the interrupt until the master can service the interrupt. This minimizes the host’s interrupt service response for fast moving inputs. 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 SPI address and allow up to two devices to share the same SPI bus.
