PCA9674; PCA9674A: 带有中断的Fm+ I2C总线远程8位I/O扩展器
PCA9674和PCA9674A通过两路双向总线（I²C总线）为大多数微控制器系列提供通用远程I/O扩展且是快速模式Plus (Fm+)系列的一部分。
PCA9674/74A是PCF8574/74A的即用升级产品，提供更高的快速模式Plus I²C总线速度（1 MHz相对400 kHz）以使输出能够支持LED的PWM调光；提供更高的I²C总线驱动（30 mA相对3 mA）以使总线上可存在更多的器件而无需进行总线缓冲；提供更高的总封装灌电流能力（200 mA相对100 mA）以支持同时打开所有的LED以及提供更多可用的器件地址（64相对8）以允许总线上存在更多器件而不会发生地址冲突。
器件由8位准双向端口和I²C总线接口组成。PCA9674/74A具有低电流消耗且包含具备25 mA高电流驱动能力的锁存输出，用于直接驱动LED。
它们还具有中断线路(INT)，可连接至微控制器的中断逻辑。通过在此线路发送中断信号，远程I/O可通知微控制器其端口上是否存在输入数据而无需通过I²C总线通信。
内部上电复位(POR)或软件复位序列引脚会将I/O初始化为输入。
