PCA9570 Remote 4-bit general purpose outputs for 1 MHz I2C-bus Rev. 5 — 16 November 2017 Product data sheet 1. General description The PCA9570 is a CMOS device that provides 4 bits 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 PCA9570 is a streamlined GPO that consists of 4-bit push-pull outputs that offer low current consumption, small packaging options and a low operating voltage range of 1.1 V to 3.6 V. The latched outputs are symmetrical 4 mA current drive capability at 3.3 V to drive various control logic.
