I understand BCD and the 74210 code looks okay, but how do i start design ing an encoder that will take BCD to 74210 code?

 

I am very familiar with BCD or Binary Coded Decimal but I am unfamiliar with "74210 code". Can you please clarify what you mean by the reference to "74210 code"?

The 74210 code is actually a binary number with 5 bits i.e 10100 being number 9.This code must have at least 2 1's or it will be an error. i.e 00011,00101,01001 etc.

This code is also called a 2 out of five code for obvious reasons.I hopt this helps
