Hello,

How to understand or read below mentioned line for Hysteresis

>>Hysteresis 0.2 volts around 7.62 volts.

Best Regards,

This line does not appear in the datasheet.

But I guess this means the two thresholds are 7.52 V and 7.72 V.

Thanks Clemens!!

Yes, it is not mentioned in datasheet but how did you calculated these two values?

Thanks,

Hi Kiranjit,

Hysteresis essentially creates two dc threshold levels for the inputs to traverse through. If the hysteresis is a total of 0.2V, centered around 7.62V, then you VH level would be 7.62V + 0.1V = 7.72V and VL is 7.62 - 0.1V = 7.52V. Section 9.2 of the datasheet has an example.
