LTC4301 与电源无关的可热插拨型双线式总线缓冲器
LTC®4301是一款独立于电源的可热插拨型双线式总线缓冲器，允许在带电背板上进行 I/O 卡板的插拨，而不会损坏数据和时钟总线。此外，LTC4301还允许 VCC、SDAIN 和 SCLIN 上拉电压与 SDAOUT 和 SCLOUT 上拉电压彼此无关。控制电路可保持背板与插件板之间的隔离，直到出现一个停止位或总线空闲状态为止。当背板与插件板相连时，LTC4301将提供双向缓冲，从而保持背板与插件板电容之间的隔离。
在插入操作期间，SDA 和 SCL 线被预先充电至 1V 以最大限度地抑制总线扰动。当被驱动至低电平时，/CS 输入引脚将允许器件在出现一个停止位或总线空闲状态之后连接。将 /CS 引脚驱动至高电平将导致 SCLIN 与 SCLOUT 以及 SDAIN 与 SDAOUT 之间的断接。READY 输出引脚的状态指示背板与插件板侧是否连接在一起。
LTC4301采用 8 引脚 DFN (3mm x 3mm) 和 MSOP 封装
