Kindly define what is Latch and what is flip flop.

Also tell me where we use Latches and where we use flip flops?

In Microcontrollers contains Latches or Flip flops?

 

Hello,

On this page you can find out the difference between latches and flipflops.

A clocked latch is level triggered. If the clock is in the active state, the Q output will follow the D input. When the clock switches to the inactive level, the output will be held in the state it was in when this occurred.
A clocked D flip-flop will transfer the level on the D input to the Q output whenever the active clock transition occurs. The output will stay at that level until the next active clock transition occurs. The JK flip-flop is similar, except the output state will be a logical function of the two inputs at clock transition time.
For example, a 7474 is clocked when the clock input transitions high. The transition to low has no effect on the output.
