I have beenb using and old ESP32 and SN74AHCT125N as level shifter. But I have a Q now. On the SN74AHCT125N, at pin 14 is the power in (5V). I can't see any pin for 5v in. Does it take power in to level shifter from the USB power in, I don't need any spec 5v input beside the USB power? |

Yes, the internal level shifter takes 5v from USB, no need to provide it in other way. |
