You guys have posted some great info, thanks!

Is there a NPN equivelent to the PN200?

What I can do is use PN200 on switching the ground side of the leds and the NPN's from the SX28 outputs.

I have posted the schematic but it is using a pic and I want to use the SX28.

Can all of this be controlled from the SX28 since it has enough I/O's without having to use a decoder chip?

The schematic is attached but the 74ls174 should be a 74ls138!

Thanks,

K
