PCA9670D, PCA9670 Remote 8-bit I/O expander

PCA9670D Description

PCA9670 Remote 8-bit I/O expander for Fm+ I2C-bus with reset Rev.3 * 30 May 2013 Product data sheet 1.General .
The PCA9670 provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).

PCA9670D 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

PCA9670D Applications

* and the latched output ports have 25 mA high current sink drive capability for directly driving LEDs. The PCA9670 has three hardware address pins and allows up to 64 of these PCA9670 I/O expanders on the same I2C-bus without the need for bus buffers, supporting up to 512 I/Os (for example, 512 LEDs)
