THVD2410: Glitch during DE signal transition

Tool/software:

Hi Team,

Customer tie DE and RE pin together and have 100k-ohm pull down.

We face to glitch issue when DE pin transition, I found a similar question from E2E" ID#1331303". In this post, if RE/DE tie together, the transition time from high to low or low to high need to be quick.

May I know the transition timing requirement to avoid device enter undefined range?

Regards,

Ben

Hi Ben,

Could you provide more information about your glitch issue with the DE transition? Is there only a glitch when going from DE high to low? How long is the glitch period?

Some waveforms of DE/RE and R would be helpful.

There is no defined transition timing requirement to avoid that undefined range, but it should be in the nanosecond range.

Regards,

Ethan
