Working of a Logic Level Shifter

This video explains the working principle of a logic level shifter and how to use one.
To buy logic level shifters:

Nicely Explained!! Good Job!

[@swishpan]

Well explained. Did you mention the other direction from 5v?

[@gianlucacastro5281]

Good explanation

[@omkarkhade4602]

Thank you

With the same circuit, can I interface 12v at HV side and 3.3v at LV side.
The reason I ask is... I want to interface a npn or pnp photo electric sensor to the stm32

[@anilph7822]

Ok nice what about the other direction boss? ie 5 to 3.3v conversion

[@daminipatel3668]

Can we connect gate terminal to 5v??
And if it do so what is the output??

[@monimonish302]

super explanation,one doubt-->1.four channel means internally it has four mosfets?
2.can it also convert from ttl to cmos signal level?

[@subhamdas2491]

Can I able to shift 400 milivolt ,-400 milivolt to 1,0 volt by this

[@thulasidasmenon1014]

out put is inverted? if input is one fet conduct output is then 0, i think this is a inverted level shifter
