Hi,
Please give me detail information about flip-flop and latch difference with examples where these are used.

Thanks

"The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does. "

I would like to add:

A Flip-Flop is normally edge triggered into one of two states:
Clock and Data input (D type 74HC74,74HC574)
OR
Combination of Set, Reset, Clock & Data (Master/Slave J-K type 74HC73)

A Flip-Flip cannot be transparent


A Set-Reset Latch output is edge triggered on or off by Set/Reset inputs.

A Transparent Latch
The Output will follow the Input (transparent) until the control input 'freezes/latches' the Output (latched condition).
It is Level controlled not edge triggered. (74HC373/573)


hope this helps ... Polymath
