Sorry for incomplete information.
Here's the whole story ... Currently I am testing a prototype of my project using PC LPT port which will finally be replaced with a 8051.There are only 12 data ports in LPT port and my interface needs 4 more. I had come across a cheap I/O expander circuit some time back but now i am unable to trace it. Thank you Regards |
