可热插拔双线总线缓冲器

TCA4311A 是一款可热插拔型 I2C 总线缓冲器，支持在带电背板上进行 I/O 板卡的插拔操作，而不会损坏数据和时钟总线。 控制电路可防止背板与板卡相连接（直到背板上出现停止命令或总线空闲为止），而不会在板卡上发生总线争用的情况。 当建立连接时，该器件可提供双向缓冲，从而使背板及板卡电容保持隔离。 在板卡插入过程中，SDA 及 SCL 线路被预充电至 1V，以最大限度地减小对芯片的寄生电容进行充电所需的电流。\n 当 I2C 总线空闲时，可通过将 EN 引脚设定为低电平来把 TCA4311A 置于停机模式之中。 当 EN 引脚为高电平时，TCA4311 将恢复正常运作。 该器件还包括一个 • 2.7V 至 5.5V 工作电源电压范围 \n• SDA 和 SCL 线路经过缓冲，因而增加了扇出\n• SDA 和 SCL 输入线路与输出隔离\n• 抗噪声性能有所改善\n• 低 ICC 芯片停用模式：2C 引脚\n• 闩锁性能超出 JESD 78 II 类规范要求的 100mA\n• 200V 机器模型 (A115-A)\n• 1000V 充电器件模型 (C101);
