hi all
i use AT89S52 which is 8051 micro
i interface the micro woth M74HC151B1 to increase the number of input pins
now how i can demultiplexing the 8's inputs internal the micro itself
and how i generate the three addresses to select the first input to go to the micro then the second and so,on 0101010101..../001100110011..../000111000111.... continuaslly
pls see the M74HC151B1 datasheet to now what i mean
thanks
