I want to find an IC(not gate) that works with 5v input and sends 12v output. Probably there are some ICs that the output varies according with the Vcc.
Can someone help me with this issue?
Almost any of the FET Gate driving ICs will input TTL levels (3.3 or 5V) and output (what ever the supply voltage is like 12V).
The old CD4000 and MC14000 series of ICs can run form a 12 volt supply so the output will be 12 volt. One of the parts inputs 5 volt TTL signals. I don't have time to look it up now.

Look at CD4101, mc14104, HE4101, HEF4101.
