Description: Remote 8-bit I/O expander

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

Applications

* and the latched output ports have 25 mA high current sink drive capability for directly driving LEDs. The PCA9674 and PCA9674A are identical except for the different, non-overlapping slave address. The three hardware selectable address pins can be decode to 64 addresses for the PCA9674 and 62 addres
