Mikebits Well-Known Member Jul 7, 2008 #2 Did not Kchriste answer this for you in one of your other threads? The 74HC238 will give you active high outputs. The 74HC138 will give active low outputs. The HCF4028 is also a good choice. Have fun. Click to expand...

R richacm New Member Jul 8, 2008 #5 Cool, thanks again! This is exactly what I'm looking for...I knew there had to be one out there somewhere. I just wanted my outputs to be consistent with the rest of my pins being 5V for on and 0V for off. Otherwise it would start to get messy. Craig
