1 General description
The PCA9574 is a CMOS device that provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion in low voltage processor and handheld battery powered mobile applications and was developed to enhance the NXP family of I2C-bus I/O expanders.
The improvements include lower supply current, lower operating voltage of 1.
1 V to 3.
6 V, dual and separate supply rails to allow voltage level translation anywhere between 1.
1 V and 3.
6 V, 400 kHz clock frequency, and smaller packaging.
Any of the eight I/O ports can be configured as...
