[sdiy] Amplifying logic signals

[Happy Harry]

AFAIK the 4049 / 4050 can only translate from a higher
voltage to a lower voltage. There are some level shifters
such as 40109 or MC14504...  I do not recommend them as
the simple solution.

How about two NPN transistors and three (maybe 4) resistors ?
