I2C总线扩展器

P82B715是一款双极IC，主要用于IC总线和衍生总线系统应用。在保留IC总线所有工作模式和功能的同时，它允许通过缓冲数据(SDA)和时钟(SCL)线路来延长I2C总线上组件之间的实际间隔距离。\n400 pF的IC总线电容极限会将实际通信距离限制为几米。在长电缆的两端分别使用一个P82B715（连接Lx/Ly至Lx/Ly ）会将所链接IC总线上的电缆负载减少10倍，允许总系统电容负载（连接至IC总线的所有器件、电缆、接口、走线或电线）变为大约3000 pF，同时保持各IC总线Sx/Sy侧上的负载仍低于400 pF。更长电缆或低成本、通用配线可用于链接基于IC总线的模块，而不会使噪音容限下降 提供双路、双向、统一电压增益缓冲器，无需外部方向控制\n兼容I2C总线及其衍生产品SMBus、PMBus、DDC等\n逻辑信号电平可包括（但不超过）电源和接地\n可独立于VCC不作更改地输出逻辑信号输入电压电平\nx10阻抗转变，但不改变逻辑电压电平\n供电电压范围为3 V至12 V\n时钟速度至少为100 kHz而允许其他系统延迟时为400 kHz\nESD保护：按Mil. Std 883C-3015.7超过2500 V HBM，按JESD22-A115超过400 V MM（I/O通过二极管连接至VCC和GND）\n已按照JEDEC标准JESD78完成闭锁测试，超过100 mA;
