PCA8574TS

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;
