PCA9535 PCA9535C 16bit I2C bus
<P>The PCA9535 and PCA9535C are 24-pin CMOS devices that provide 16 bits of General<BR>Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was<BR>developed to enhance the
PCA9535 PCA9535C—带中断的低功耗16位I2C
<p>PCA9535/ PCA9535C是24脚的CMOS器件，它们提供了I2C/SMBus应用中的16位通用并行输入/输出口（GPIO）的扩展，该器件使PHILIPS的I2C I/O扩展器件系列得到增强。改进的特性包括更高的驱动能力、5V I/O口、更低的电源电流、单独的I/O口配置、更小的封装形式。当应用中需要额外的I/O口来连接ACPI电源开关、传感器、按钮、LED、风扇等时，可使用I/O扩
