Is there a limit to the input rise and fall time of the ADN4667?

Thread Summary

The user inquired about the maximum allowable input rise and fall times for the ADN4667, noting discrepancies between revisions of the datasheet. The support engineer clarified that the rise and fall times specified in the datasheet refer to the output driver performance, and there is no specific limit for the input rise and fall times. The user was concerned about potential negative effects from long periods in an undefined state, but the engineer reassured that this is not an issue.

Product Number: Is there a limit to the input rise and fall time of the ADN4667?

Dear Specialists,

I would like to know the maximum allowable input rise and fall times for the ADN4667.

I checked the AC CHARACTERISTICS in the data sheet.

However, the descriptions differ depending on the revision, and I am confused.

In Rev.0, it says "Rise Time, tr".

In Rev.B, it says "Rise Time, tTLH".

I looked for clues from similar products.

In the data sheets of the ADN4665 and ADN4663 Rev.0,

it says "Parameter: Rise Time, Symbol: tTLH".

Based on these results, I believe that the description in Rev.B of the ADN4667 data sheet is correct.

However, that assumption means that I cannot obtain the maximum input rise and fall times from the data sheet.

Therefore, I am in a situation where I need help.

I would appreciate your cooperation.

Best Regards.

Ryo.
