Hi team,

can you help to confirm that:

1. can we design system based on TYP 0.65V? the 0.65V can't ensure 100% high level recognition right?

2. can we ensure the high level if we design system based on the MIN value 0.9V?

3. do we have a distribution plot/data for the VIH spec?

Hi Dane,

It means that we can ensure the device power on when EN voltage is 0.9V but it's not sure if a device can power on when EN is 0.65V.

In design, we should make sure EN voltage is higher than 0.9V when we want to turn it on.

Thanks.

Best Regards,

Shipeng

Hi Shipeng,

thanks for the reply. can you help to see if we have data that show the distribution of the Vih spec?( ex: within a certain amount devices tested, the number of device allocated in different Vih area?)
