Binary counter is the same as Hex counter. Use "Binary counter circuits" pang google.
Ang problem is how to display hex A,B,C,D,E,F. The common TTL 7447 does not display valid hex numbers. The CMOS 4511 blanks the display for non-decimal values. Googling, the DM9368 can display HEX.
Yan ah, spoon fed na halos.
