But DC Analysis fails because of lower VOH. [2.4 (VOH) -2.9 (VIH)=-0.5]<BR /><BR />Please suggest me with MPN for converting these 3.3V UART signals to 1.8V UART Signals.<BR /><BR /></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ramkrish_0-1759844362684.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/359756i2607A6BEC61B5F71/image-size/medium?v=v2&amp;px=400" role="button" title="ramkrish_0-1759844362684.png" alt="ramkrish_0-1759844362684.png" /></span></P><P>&nbsp;</P> Tue, 07 Oct 2025 13:48:23 GMT https://community.nxp.com/t5/Other-NXP-Products/SC16IS740IPW-VOH-DC-Analysis/m-p/2181234#M30274 ramkrish 2025-10-07T13:48:23Z https://community.nxp.com/t5/Other-NXP-Products/SC16IS740IPW-VOH-DC-Analysis/m-p/2181376#M30281 <P>Hello ramkrish</P> <P>Good day!</P> <P>For simplicity, I would recommend using the NTS0302JK, which already has a table in the <A href="https://docs.nxp.com/bundle/NTS0302/page/topics/general_description.html?_gl=1*7exnh5*_ga*MzQyOTU3MDU2LjE3NTk4MjI1MDM.*_ga_WM5LE0KMSH*czE3NTk4NTIxMzAkbzMkZzEkdDE3NTk4NTMwMzYkajIzJGwwJGgxMTE4MzgyMDM." target="_blank">datasheet</A> with recommended voltage and current ratios for use.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="RafaR_0-1759857295318.png" style="width: 448px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/359779iB5123C317C08EA76/image-dimensions/448x149?v=v2" width="448" height="149" role="button" title="RafaR_0-1759857295318.png" alt="RafaR_0-1759857295318.png" /></span></P> <P>&nbsp;</P> <P>I hope this information has helped you, please let me know if you need help with anything else.</P> <P>Have a great day and best of luck.</P> Tue, 07 Oct 2025 17:15:40 GMT https://community.nxp.com/t5/Other-NXP-Products/SC16IS740IPW-VOH-DC-Analysis/m-p/2181376#M30281 RafaR 2025-10-07T17:15:40Z
