I was trying to design a digital clock.I managed to build a 60Hz clock generator using 555 timer,but now I need to divide it by 60.I can use a decade synchronous counter cascaded with a divide by six counter as i found in text book.But i just can't find the IC no of a DIV-6 counter.Can you help me please?

A much better alternative is a 4060, which has a quartz oscillator schematic. Take a look at this data sheet...

The chip will get you to a 2 hz clock with a watch crystal and a small handfull of parts. The same built in oscillator can be used as an RC oscillator also. A good website for chips is...

If you just have to have a divide by 6 then check out the 7492.

 

Hello,

You could use a 74LS92.
This is an divide by 2 and a divide by 6.
See datasheet.

You can use a decade counter as a divide by 6. Connect its sixth output to the reset and it will divide by 6.

 

Most decade counters have a BCD output. The way to make it short count before 9 would be to AND bit 1 plus bit 2 for the reset at the count = 6.

 

I think you need to specify the tecnology which ou wish to use. It can be TTL or CMOS.
