placing high to low level shifter

[fragnen]

Should low to high level shifter be placed in high voltage domain and why?

 

[wwfeldman]

I'm not an exert on level shifters, however, I will state what seems obvious:

the level shifter has to go between the low and high levels, with the
zener diode / transistor / resistor that accomplishes the level shift
placed between the low and high levels.

i'm not sure what you mean by "be placed in high voltage domain".
why is always a good question

A practical point to declare 'high' voltage... when touching it shocks us. Around 50 volts.

If VH is already in ASIC ,why not, but not needed in VL , why bother adding another pin.

Otherwise 2 pts. for a very vague digital question.
