What is different EP4CE6F17C8N and EP4CE6F17C8NAD - What is different EP4CE6F17C8N and EP4CE6F17C8NAD Hello We used EP4CE6F17C8N without problem, but we used EP4CE6F17C8NAD mixed and had problems only with this product. So I want to know what's the difference between the two products Thank you Replies: Re: What is different EP4CE6F17C8N and EP4CE6F17C8NAD Hi Thank you for your reply. The picture above is the waveform of the nCSO pin during initial startup. The left is GOOD, but right (AD) is NOT GOOD. What do you think is the problem?
