PCA9672D
Overview
The PCA9672 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 30 mA drive I2C-bus interface, three hardware address inputs and a reset input operating between 2.3 V and 5.5 V. 1 MHz I2C-bus Fast-mode Plus (Fm+) can support PWM dimming of LEDs, and higher I2C-bus drive 30 mA allows more devices to be on the bus without the need for bus buffers.
