Hello,
We are working on a project with SN74LVC126AQPWRQ1 in it.
Kindly review the attached schematics and let me know the review comments.
Hi Melbin,
Thanks for the opportunity to review your schematics.
It looks like you're using the SN74LVC126A-Q1 to buffer multiple UART signals.
The parts that I can see on the schematic are fine. I do wonder if you are using the OE pins at all -- if so, are the outputs being defined during that time? I don't know what the load is, but you may need to add pull-up or pull-down resistors to keep the outputs defined when they are in the high-impedance state. This will depend on what they are driving.
Similar to the first post I responded to (on the SN74LVC1G08-Q1), I can't see the input signals or output load, so I can't really comment on those besides saying keep the input signals fast and near the rails, and the outputs lightly loaded (within datasheet specs).
Hey Melbin,
The circuits look fine.
Melbin,
I noticed that you have already posted this. In an effort to consolidate posts on E2E, I have merged the threads.
Best,
Danny
