Description
The PCA9557DGVRG4 is an 8-bit input/output expander designed for SMBus and I2C applications. It features an 8-bit input port register, 8-bit output port register, and an I2C/SMBus interface. The PCA9557DGVRG4 has a low current consumption and a high impedance open drain output pin, I/O0. The device can be enabled by the system master to operate as either input or output by writing to the configuration register.
