Hi,

I am using ST2378 level shifter to read the data from 5V operated LCD from a MCU operating at 3.3V
I am able to wright the data on LCD but not able to read the data from LCD.
I tried three LCD from different make (manufacturer). out of that 1 LCD data I can read but two LCD data I am not able to read.
As voltage shifter is bidirectional OE pin connected to 3.3V.
 

Hi,

you surely know that we don´t know
* your schematic
* your timing
* your code

So, how can we help?

Klaus
