Could you please advise how much hysteresis does the logic input pins have?

Hi,
Let me look into this and see if we have any documentation

Hi Shinji,
why do you ask? From the datasheet a logic high is 2V and logic low is 0.8V. I would assume that the hysteresis is 1.2 V, or rather the Schmitt trigger latches "high" at 2V and "low" at 0.8V

Hi Arthur,
Thank you. Let me double check.
Once logic is latched High(Low), it will not turn Low(High) until 0.8V(2.0V).
It means there is no input condition to make logic unstable, correct?

Hi Shinji,
I did a bit more searching around E2E, and I think that this part is not actually a Schmitt trigger input, because if it was then in the electrical characteristics section of the D/S there would be a V_t+ and V_t- spec given.
Unfortunately, I can not provide a number for the hysteresis on the input pins. if the signal is specially slow or noisey it may be best yo use and external true Schmitt trigger.

Arthur
