SN74LVC1G125: SN74LVC1G125 Voutput min undershoot spec

Part Number: SN74LVC1G125

Hi Sir,

If we have -1.14V undershoot in SN74LVC1G125 output pin, is it cause any possible to damage?

measurement waveform as below, please help to advice it,

Thank you

  • Anne,

    This goes beyond the abs max rating however as long as the clamp current stays below its max rating it should be okay. I see that it spikes quickly so there may not be cause for concern, but again it depends on the amount of current going through the protection diodes during that spike. What is connected to the output? I'm curious about whats causing this.
