brief introduction: Introduction:Latches are simple electronic component, which is designed to hold a memory state within its parts. They are also part of the bistable multivibrator family, which means that the output can maintain a steady state in two different voltage outputs. It also means that the output voltage is dependent on both what the current output state of the latch is as well as what the current input state is. The combination of these two in some way determines what the new output is going to be, but
