PCA9672D, PCA9672 Remote 8-bit I/O expander

PCA9672D Description

PCA9672 Remote 8-bit I/O expander for Fm+ I2C-bus with interrupt and reset Rev.3 * 27 May 2013 Product data sheet 1.General .
The PCA9672 provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).

PCA9672D 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

PCA9672D Applications

* and the latched output ports have 25 mA high current sink drive capability for directly driving LEDs. The PCA9672 has two hardware address pins, allowing sixteen of each device to be on the same I2C-bus without the need for bus buffers, so there can be supporting up to 128 I/Os (for example, 128 LED
