#110676 - why
Responding to: ???'s previous message
I've looked at the LPC with built-in LCD drivers but I really want to use a 5V device.

I know that as someone that has been dragged, kicking and screaming, to 3V3 I should be the last to ask "why".

However, once you get there and have taken enough Pepto-Bismol to cure the heartache associated with the transition, it becomes just as "natural" as 5V was. My resistance to 3V3 was motivated/excused by the lower noise margin and I kept saying no on that basis. When, finally, I had to go 3V3 (needed the 100MHZ SILabs gives you) I found, much to my surprise that there was no detoriation.

With the exception of a few manufacturers that try to make a nice market by making new chips to supply anachronistic designers all new chips relevant to this come out in voltages less than 5V.

Thus, since you will have to take the step some day, why not take it today?

PS When you switch, you will find taht the 74LVC4245 is a true friend
