Again a question about the 4 Channel Logic Level shifter (#2595):
I have 7 data channels going into my project (different volage levels from outside, 3.3V internally), 6 with 3.3-5V <-> 3.3V and 1 with 5-7V <-> 3.3V.
So I’m using two of those logic level shifters for the 6 3.3-5V channels, which is a waste of 2 channels. As I’m running out of space, I would like to cut down the third levle shifter to just one channel.
After studying the traces on both sides of the PCB, it looks to that its possible to:
cut off the last channel, which is not really usefull as it doesn’t save much space and its easy to damage another channel:
cut off all but the first channel, which makes a one channel level shifter that is smaller than hand-solderable parts with the same function:
It is not possible to cut off two channels, because of one trace going all arround the PCB.
Are those findings correct?
I think it would be nice to have different versions of this very usefull little tool. So, what about 1-, 2-, 6- and 8-channel level shifters? (Or a version that is designed to be cut to taste?)
