PCA9570
正常供应

PCA9570是一款CMOS器件，为低压处理器和手持电池供电移动应用提供4位通用并行输出(GPO)扩展。它以1 MHz I²C‑总线速率运行，同时与快速模式(400 kHz)和标准模式(100 kHz)保持向后兼容性。

PCA9570是简化的GPO，由4位推挽输出组成，提供低电流消耗、小型封装选项和1.1 V至3.6 V的低工作电压范围。锁存输出在3.3 V时为 对称的4 mA电流驱动能力，可驱动各种控制逻辑器件。在保持互连和最小占地面积的同时需要额外的输出时，PCA9570输出扩展器提供简易的解决方案，例如，在拥挤的PCB上来连接传感器、按钮等附件的电池供电移动应用中。

PCA9570包含内部上电复位(POR)和软件复位功能，可将器件初始化为默认状态。
