Hello,
Our customer use ISO7521C.
However, since there are the Glitch impulse in their boards, the ISO7521C output was latched High.
Thus, there are the problem in their product.
Then I propose the ISO7821 for replacement from the ISO7521C.
They would like to evaluate the ISO7821 but they need the document which explain the ISO7821 don't latch and ISO7521C is latched high when glitch input.
Could you please share the document that exlain the difference of ISO7821 and ISO7521C if there are glitch input ?
I already propose the application note of "Digital Isolator Design Guide".
However they don't accept it due to there is no description of behavior when glitch input.
Please kindly help us.
If you can't share the document in this forum ,please contact to the following e-mail address.
