LTC4300A-3 具启用功能的电平移位可热插拔两线式总线缓冲器
LTC®4300A-3 可热插拔两线式总线缓冲器允许 I/O 板卡插入带电背板，而不损坏数据和时钟总线。当建立连接时，LTC4300A-3 可提供双向缓冲，从而使背板与板卡电容保持隔离。上升时间加速器电路允许使用较弱的 DC 上拉电流，同时仍然满足上升时间要求。在板卡插入期间，SDA 和 SCL 线路预先充电至 1V，以最大限度地抑制总线扰动。
LTC4300A-3 可提供 3.3V 和 5V 电源之间的电平转换。背板和板卡均可采用介于 2.7V 至 5.5V 之间的电源电压进行供电。另外，LTC4300A-3 还包括一个 CMOS 门限 ENABLE 引脚，该引脚负责强制器件进入一种低电流模式，并将板卡与背板隔离开来。当驱动至 VCC 时，ENABLE 引脚设定正常操作。
LTC4300A-3 采用 MSOP 封装和 3mm x 3mm DFN 封装。
