Part Number: ISO3080
Other Parts Discussed in Thread: ISO3082

Hi,

Does the receiver of ISO3080 have hysteresis function?
Datasheet diagram does not show hysteresis against ISO3082/8 diagram.

Best regards,
Shimizu

    Hi Shimizu,

    Thanks for the question!

    The receiver does have hysteresis. If you look at Section 6.9 Electrical Characteristics: Receiver (page 8 of the ISO308x datasheet) you can see that the Positive-going input threshold voltage is -85 mV and the Negative-going input threshold voltage is -115 mV totaling a 30 mV of Hysteresis voltage.

    Let me know if you have any other questions!

    Best regards,
    Dan
