Which logic level converter to choose from 3.3V to 5V?

Which converter to choose from 3.3V to 5V?
Options to solder, for example, a cascade with a common emitter or use a field-effect transistor, do not offer it as a key, because. there will be quite a lot of output signals. The output should be a non-inverted signal, amplitude 5V.
I'm not strong in circuitry, but maybe this is 74lvc244 or sn74lv1t34dbvr

the indicated microcircuits are suitable, but they are just buffers. the decision is correct but crutch.
from here choose a more "correct" solution for the required number of channels and additional options. example - 74LVC4245APW,118

Do you want simple, reliable and forever?
Get an optocoupler.
