Electrical – Raspberry Pi with 74HC14 connecting to LED strip (WS2812B)

led striplevel-shiftinglogic-levelraspberry pittl

This might be a stupid question, but I can't seem to figure out how to convert 3.3V to 5V with the 74HC14. I have a power source which can supply 5V (see the power adapter at the left), and use it to power the Raspberry Pi and the converter. The Raspberry Pi has GPIO at 3.3V, while the LED strip (WS2812B) operates at 5V. This means I would like to use a logic-level converter to convert the 3.3V from the RPi to the 5V for the LED strip.

Unfortunately, I do not have a lot of experience in schematics, nor can I find any possible location where they use the 74HC14 the way I need it. I could use any help needed!

EDIT 1:
It appears that the 74HC14 does not support 3.3V input, but as suggested by @Justme, the 74LS14 seems to work well. I also found the TXB0108, should that also be useful, or is it better to use the 74LS14?

EDIT 2:

Thanks to the comments section, I stumbled upon the 74HCT125, which might work I've updated the design based on the suggestions, is there anything wrong with it or that could be improved?

The 74HC14 does not work with 3.3V logic input when it is powered from 5V. The original schematic uses 74LS14 which does work, and for example 74HCT14 would work too.
