1-Wire、8通道、可编址开关

DS2408是一款8通道、可编程I/O 1-Wire® IC。PIO输出可配置为开漏结构，具有100Ω的最大导通电阻。稳固的PIO通道访问通信协议确保PIO输出设置变化没有误差。数据有效选通输出，可用来锁存PIO的逻辑状态，供给外部电路，如D/A转换器(DAC)或微控制器的数据总线。\n\n DS2408的工作受单线连接的1-Wire总线控制，器件通信遵从于标准的Dallas Semiconductor 1-Wire协议。每片DS2408都具有自己的64位ROM注册码，这个注册码由工厂光刻到芯片内。该注册码保证其唯一的可识别性，在多点连接的1-Wire网络中可以用作地址码。多片DS2 • 八通道开漏结构的可编程I/O \n• PIO下拉晶体管导通电阻100Ω (最大)；关断电阻10MΩ (典型值) \n• 独立的事件锁存器捕获PIO输入口线上的异步状态变化以备总线主控查询 \n• 数据选通输出实现PIO逻辑状态与外部读/写电路的同步 \n• 内置多点控制器，确保与其它Dallas Semiconductor 1-Wire网络产品的兼容性\n• 支持1-Wire条件搜索命令，响应由可编程PIO条件控制\n• 由工厂光刻的唯一64位注册码保证无差错地选择和识别器件 \n• 使用1-Wire协议，以15.3kbps或100kbps通过单条数字信号和主机通信;
