PCA9570GM4中文资料Remote 4-bit general purpose outputs for 1 MHz I2C-bus数据手册恩XP规格书

描述 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 mobileapplications. It operates at 1 MHz I²C‑bus speeds while maintaining backwardcompatibility 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 lowcurrent consumption, small packaging options and a low operating voltage range of 1.1 Vto 3.6 V. The latched outputs are symmetrical 4 mA current drive capability at 3.3 V todrive various control logic. The PCA9570 output expander provides a simple solutionwhen additional outputs are needed while keeping interconnections and floor space to aminimum, for example, in battery powered mobile applications where PCBs are crowdedfor interfacing to sensors, push buttons, etc.
The PCA9570 contains an internal Power-On Reset (POR) and a Software Reset featurethat initializes the device to its default state.
