PCA9674A - NXP Semiconductors

PCA9674A 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 dev.
