LGC, Email Technical Support, www.ti.com, SN74LVC2G17Hello, It's not really a problem. part number SN74LVC2G17 (series) Two Things: 1) I plan on using your device as a voltage translator. I'm tieing 5 volts to the VCC and injecting 3.3V. So a logic 1 will be 5V and logic 0 will be 0 Volts. In other words 3.3V in and 5V out 2) Just the opposit as above: Vcc = 3.3volts. Logic 1: 5V in 3.3V out Logic 0: 0V in 0V out Will this part work as a voltage translator?

Hello Brian
For down translating this part will work Ok. You can set Vcc to 3.3V and have 5V inputs and your output will be 3.3V.
It will not work going the other way. Vih on a schmitt trigger is VT+Max. It will be slightly over 3.3V.
The LVC2G34 would work both ways but would not have the scmitt trigger output.

I corrected the last line. I said output but meant input
