BCD counter

[Kevin Weddle]

I was looking for an ordinary counter, but I only found a BCD counter. It turns out that it works the way I wanted it to. I had planned on using a regular counter fed to a decoder. Each sequence would decode one output. This is what this device does. Maybe we should call this a counter/decoder instead of a BCD counter.

Kevin,
Are you using a 4017 chip?
Both Texas Instruments and Fairchild call it a "Decade Counter/Divider".

Try a 4060 binary counter with built-in oscillator, and listen to its octave-divided outputs. But it is a "ripple" counter, so you can't easily gate-decode its outputs, and some outputs are missing from the sequence.

A 4040 is a long binary ripple counter without oscillator, that has all 12 outputs in sequence. It divides its clock from 2 to 4096.
