hey,

are there any low cost alternatives to the 74HC4511?

Cheaper the better, failing that would it be less expensive to knock one together from discrete logic... (if i did this would the propagation be significantly worse than in the IC package??)

please help!

There's always a CMOS CD4511.

 

or the 7447 (which has a pinout extremely close). Unit cost is less than $1, you can not build or DIY cheaper than that.

 

Or you can use a shift register. Then you can get all kinds of configurations other than just numbers. I did this to get hexadecimal numbers.

 

Thank you for your replies,

I think a shift register would be a bit overkill for what i'm planning on making, plus wouldn't it require further logic in order to drive the 7segment?

The other chip however, looks like a go-er. Cheers for your help!
