Remote 8-bit I/O expander
The PCA9674/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)). The devices consist of eight quasi-bidirectional ports, 1 MHz I2C-bus Fast-mode Plus (Fm+) family interface, with high speed data transfer it can support PWM dimming of LEDs, and higher I2C-bus drive 30 mA for more devices can be on the bus without the need for bus buffers. Three hardware address inputs and interrupt output operating between 2.3 V and 5.5 V. The quasi-bidirectional port can be independently assigned as an input to monitor interrupt status or keypads, or as an output to activate indicator devices such as LEDs. The system master can read...
