LM339LV: Power-On Reset

Carlo
Expert 7715 points
Part Number: LM339LV


Hi E2E


Good day.


Based on the datasheet, the output will be in the high-impedance state if the power supply voltage is too low. However,  Figure7-1 Power-On Reset Timing Diagram shows it pulling down in that state. 


Your clarification on this is appreciated.


Regards,
Carlo

    Hello Carlo,

    Yes. You are correct. That seems to be the wrong graphic. Thank you for bringing it to our attention. We'll fix it on the next update.

    As the text states, the output will be Hi-Z (not sinking) until the end of the POR period.
