EP1C6T144C8的io口如何驱动5V电源的CMOS器件： 

 

如果5V电源的器件的VIH高于3.5V，而EP1C6T144C8的io的VOH最高是3.3V，那么，EP1C6T144C8的io口如何驱动5V电源的CMOS器件？ 

 

EP1C6T144C8与5V器件之间必须加电平转换芯片才行吗？还有没有其他解决方案？ 

 

EP1C6T144C8的DATASHEET哪一部分讲了这个问题？

cycloneIII_3c25_start_kit 的做法。 

 

 

Place one voltage transform chip between the two chips.
