The PI4IOE5V9570 is a CMOS device that provides 4bits of General Purpose parallel Output (GPO) expansion in low voltage processor and handheld battery powered mobile applications. It operates at 1 MHz I2C-bus speeds while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz). The PI4IOE5V9570 is a streamlined GPO that consists of 4-bit push-pull outputs that offer low current consumption, small packaging options The PI4IOE5V9570 output expander provides a simple solution when additional outputs are needed while keeping interconnections and floor space to a minimum, for example, in battery powered mobile applications where PCBs are crowded for interfacing to sensors, push buttons, etc. The PI4IOE5V9570 contains an internal Power-On Reset (POR) and a Software Reset feature that initializes the device to its default state.
