Description:

Remote 8-bit i/o expander.

PCA9672, Remote 8-bit I/O expander

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

PCA9672 Features

* I2C-bus to parallel port expander

* 1 MHz I2C-bus interface (Fast-mode Plus I2C-bus)

* 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 to inputs at power-up

* Latched outputs with 25 mA
