ok, i see an IC, but I am not sure if it is the IC i need...
MC14495...
im studying its datasheet right now, thanks btw...
~yes i am new here in PF, thanks for welcoming...Overwhelming...^_^
guys, you just created a circuit a BCD 4bits Full adder but in my case i just need a 3bits-3bits addition so that i set the A4 to 0 by default...
i used 7483 for 4bits full adder and connect it to a 7447 BCD to 7-segment
A4A3A2A1 + B43B2B1
A4 & B4 are set to 0
so 7 is the maximum...
