SR. NO.
ASYNCHRONOUS SEQUENTIAL CIRCUIT
SYNCHRONOUS SEQUENTIAL CIRCUITS.
1 Output can be changed at any instant of time by changing the input
Output changes at discrete interval of time
2 The status of memory element will change any time as soon as input is changed. It does not use a clock
The status of memory is affected only at the active edge of clock, if input is changed. It uses a clock pulse.
3 These circuits are easy to design
These circuits are difficult to design.
4 They are slower as compare to synchronous.
They are faster as compare to asynchronous.
5 Asynchronous is wherein all the flipflops within the counter do not change state simultaneously. This is because all the flip-flops are not clocked simultaneously. 
Synchronous is wherein all the flip-flops within the counter change state simultaneously. This is because all the flip-flops are clocked simultaneously.
