PCA9516AD: 5通道I2C总线集线器

PCA9516A是一款CMOS集成电路,主要用于I²C总线和SMBus系统应用。

在保留I²C总线系统所有工作模式和功能的同时,它允许通过缓冲数据(SDAn)和时钟(SCLn)线路以允许扩展I²C总线,从而可使用五条400 pF的总线。

400 pF的I²C总线电容极限会限制器件数和总线长度。使用PCA9516A能使系统设计师将总线分成集线器的五个区段,其中任何区段至区段转变只会看到一个转发器延迟。

它还可用于运行5 V和3.3 V的不同总线或400 kHz和100 kHz总线,当另一条总线需要400 kHz操作时会隔离100 kHz总线。

无法串联两个或多个%%/strongstrong class="ph b"%%。PCA9516A的设计不允许此配置。由于没有方向引脚,所以使用稍有不同的“合法”低电压以避免集线器中各转发器输入和输出之间的锁定状况。PCA9516A的输入上应用的“常规低电平”会在所有已启用输出上以稍高的值作为“缓冲低电平”传输。当此“缓冲低电平”应用至串联的另一PCA9515A、PCA9516A或PCA9518A时,第二个PCA9515A、PCA9516A或PCA9518A不会将其识别为“常规低电平”且不会再次将其作为“缓冲低电平”传输。PCA9510A/9511A/9513A/9514A和PCA9512A无法与PCA9515A、PCA9516A或PCA9518A串联使用,但可与其自身串联使用,因为其使用切换而非静态偏移以避免锁定状况。

1. 最大系统工作频率可能因转发器添加的延迟而小于400 kHz。
