Description
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.
