Despite exceeding the advertised maximum frequency, the component still operates correctly.</P><P>Before we proceed with mass production, we would like to know if you can guarantee that the PCF8574TS will consistently run at 250 kHz.</P><P>Thank you.</P> Tue, 24 Dec 2024 12:52:04 GMT https://community.nxp.com/t5/Other-NXP-Products/Question-about-PCF8574TS/m-p/2019101#M26914 MR444 2024-12-24T12:52:04Z https://community.nxp.com/t5/Other-NXP-Products/Question-about-PCF8574TS/m-p/2019222#M26916 <P>Hi&nbsp;<A id="link_6" class="lia-link-navigation lia-page-link lia-user-name-link" href="https://community.nxp.com/t5/user/viewprofilepage/user-id/244931" target="_self" aria-label="View Profile of MR444"><SPAN class="">MR444</SPAN></A></P> <P>Unfortunately we can't guarantee this data,please refer to datasheet mentioned.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="guoweisun_0-1735104989546.png" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/317247iE44AE2B7CE5E5856/image-size/medium?v=v2&amp;px=400" role="button" title="guoweisun_0-1735104989546.png" alt="guoweisun_0-1735104989546.png" /></span></P> <P>&nbsp;</P> Wed, 25 Dec 2024 05:37:24 GMT https://community.nxp.com/t5/Other-NXP-Products/Question-about-PCF8574TS/m-p/2019222#M26916 guoweisun 2024-12-25T05:37:24Z
