ADCS7476: ADCS7476 digital input is independent with AVDD

in datasheet discription, adcs7476 digital input voltage is independent with avdd,

is it mean that (digital input = 5V && AVDD = 3V ) or ( digital input = 3V && AVDD = 5V) allowed??

looking forward to your reply, thank you! 

Amy Luo：

您好，

这两种情况都是可以的，因为数字输入引脚限制电压与电源电压VDD无关，数字信号输入电压最大可以到6.5V，而可以识别为高电平的电压是2.4V；

另外，请注意尽管数字输入可以达6.5 V，但数字输出只能驱动VDD的电压输出。
