PCA9670, Remote 8-bit I/O expander
The PCA9670 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
PCA9670 Features
* I2C-bus to parallel port expander
* 1 MHz I2C-bus interface (Fast-mode Plus I2C-bus)
* SDA with 30 mA sink capability for 4000 pF buses
* Operating supply voltage 2.3 V to 5.5 V with 5.5 V tolerant I/Os held to VDD with 100 A current source
* 8-bit remote I/O pins that default
