I2C 和 SMBus 总线缓冲器及加速器

Analog Devices 的 I2C 器件系列可对其他数字串行两线式总线进行寻址,包括 SMBus、PMBus、ATCA 智能平台管理总线 (IPMB) 和 HDMI DDC 总线。我们的独立型或内置上升时间加速器有助于加快信号上升时间,以帮助满足 I2C 要求,而我们的软件可编程和引脚可选的 I2C 多路复用器则有助解决 I2C 地址局限性问题,增加扇入或扇出,并集成用于一体化解决方案的总线缓冲器和上升时间加速器。可通过电阻器进行配置的 I2C 地址转换器可配置为具有超过 100 个唯一的从地址,以允许具有相同地址的多个从属器件共存于同一根总线上。另外,我们的 I2C 总线缓冲器和多路复用器还可提供从 I2C 总线阻塞于低电平的自动恢复。
