Description:

Asynchronous Counters

Asynchronous counters are those whose output is free from the clock signal. Because the flip flops in asynchronous counters are supplied with different clock signals, there may be delay in producing output.

The required number of logic gates to design asynchronous counters is very less. So they are simple in design. Another name for Asynchronous counters is “Ripple counters”.

Different types of Asynchronous counters

There are many types of Asynchronous counters available in digital electronics. They are

  • 4 bit synchronous UP counter
  • 4 bit synchronous DOWN counter
  • 4 bit synchronous UP / DOWN counter
