pc parallel port spi
Hi, IanP:
Thanks a lot for your help!
It would be better if you can give more details on this figure such as suitable parts(part number) of the transistor.
Actually, after intesive searching on the Internet, I also found similar circuits that used Philips BSNxx series MOSFET to implement the general purpose bi-directional voltage shifter. In addtion, there are a lot of ICs that can achieve this kind of goal, in order to benefit everyone who viewed this post, I'd like to share some of the applications as below.
Best regards,
