Hi - I need to find a schmitt trigger buffer or inverter. It needs to be able to handle a 3.3V level input, but have a 5V output. Ideally there'd be a family with a wide range of numbers of these parts/chip. But that isn't an absolute for me.

I just went through TI's website and couldn't find anything that matched this. TI is my go to source for logic chips, for some reason. The problem seems to be the 3.3 tolerant input - most chips seem to have their upgoing threshold around 3.3V.

Can anybody suggest a part or family?

Thanks!

HCT series should work, like the HC(T)14. At 5.5V, the worst case VTh+ is 2.1V.

I was about to say I thought you were mistaken - then I realized that they give two sets of VTH+ data - one for the HC, and one for the HCT! The HCT looks like it should work just fine. Too bad it's only readily available stateside in a SOIC (would prefer a TSSOP), but oh well! Thanks!

Yup, you need 74HCT14. Also single gate chips available.
