SN74LVC1G17: Recommendation for fixed hysteresis device

Tool/software:

Hello team,

Currently my customer is using our SN74LVC1G17 schmitt trigger IC for their project.

I see that hysteresis range & output level is selected via input voltage

However, customer is looking for an IC where hysteresis range is fixed always, yet we can still select output level depending on input voltage.

Could you please share which IC would support this?

Thank you in advance for your help and support.

Hi Jade,

There is no logic device with a fixed hysteresis range. The customer would have to use a comparator for this application.

Best,

Malcolm

Hi Malcolm,

Thank you so much for your feedback!

May I ask, how can customer fix hysteresis range by adding a comparator? If there's any materials like apps note on this could you please share with me?

Thank you for your help and support.

Best regards,
Jade

Hi Jade,

Here is a reference design where a comparator with fixed levels of hysteresis is implemented: Comparator with Hysteresis Reference Design
