Hello all,
I was thinking of using my PIC at 5v but to interface with nokia LCD at 3.3v max. and then I came across this relay IC ULN2803 which drives signal HIGHER instead of lower. I wanted to ask is it OK if my input is 5v but I supply 3v to ULN2803 to get 3v signal?
or is there anything better to use?
Regards,
SKy
