Im not sure if this is the craziest question at the moment. But ....
I have a 1.8v system which sends out LCD data at well... 1.8v... i need to translate that 1.8v to 3.3v for a LCD...
Now i know about the 74xx245 which is used as a level translator but for the amount of pins it doesnt seem cost effective. I have to convert about 30 lines (40 lines at most) so i was reading something somewhere the other day and someone used a simple 74xx244 as the translator. Is this safe?
Its a LCD and there is no data going back to the main board i think. All the pins are Output type... or i assume. (no assume jokes plz)
The LCD is similar to the PSP Style LCDs but has a touch screen. The touch part does not concern me at the moment. Just the actual LCD lines. So is it possible to use a 244? or do i HAVE to use a 245 ?
This is the 74xx244 i planned on getting... $1.5 each (20 lines)
