Remote 8-bit I/O expander for I2C-bus with interrupt

The PCA8574/74A provides general-purpose remote I/O expansion via the two-wirebidirectional I²C‑bus (serial clock (SCL), serial data (SDA)).\nThe devices consist of eight quasi-bidirectional ports, 400 kHz I²C‑bus interface, threehardware address inputs and interrupt output operating between 2.3 V a I²C‑bus to parallel port expander\n400 kHz I²C‑bus interface (Fast-mode I²C‑bus)\nOperating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with 100 μA current source\n8-bit remote I/O pins that default to inputs at power-up\nLatched outputs with 25 mA sink capability for directly;
