8-bit I2C-bus and SMBus, level translating, low voltage GPIO with reset and interrupt

The PCA9574 is a CMOS device that provides 8 bits of General Purpose parallelInput/Output (GPIO) expansion in low voltage processor and handheld battery poweredmobile applications and was developed to enhance the 恩XP family of I2C-bus I/Oexpanders. The improvements include lower supply current, lowe 400 kHz I2C-bus serial interface\nCompliant with I2C-bus Standard-mode (100 kHz)\nSeparate supply rails for core logic and I/O bank provides voltage level shifting\n1.1 V to 3.6 V operation with level shifting feature\nVery low standby current: < 1 μA\n8 configurable I/O pins that default to inputs ;
