PCA9617A集成电路（IC）的信号缓冲器、中继器、分离器规格书PDF中文资料

PCA9617A属于集成电路（IC）的信号缓冲器、中继器、分离器。由安森美半导体制造生产的PCA9617A信号缓冲器、中继器、分离器信号缓冲器、中继器和分离器系列中的产品适用于远距离电气互连或电缆系统的数字信息传输。所有实际互连系统都具有非理想特性，该系列产品主要用于解决数字信息传输过程中因此造成的模拟问题。此外，还有其他功能，例如不同物理接口样式之间的转换和多路复用。

Level-Translating Fm+ I2C-Bus Repeater

The PCA9617A is an I2C−bus repeater that provides level shifting between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) for Fast−Mode Plus (Fm+) I2C−bus or SMBus applications.
