I had read another user's question about connecting a 5.0V chip to a 3.3V chip and saw that someone had suggested using the 74LVC244/245 (I understand the 245 to be bidirectional, which is what I need). I know that there are other chip options out there but I am on a budget and in a pretty tight schedule crunch and I have some 74245s on hand (actually, they are 74LS245N chips, I am hoping that doesn't change the ability to convert from 3.3V to 5.0V)

I was just curious if anyone might know how to do this, if I can just hook the power supply up as 3.3V or if there are other modifications I need to make.

Any help would be greatly appreciated!
