  • The simplest bistable device, therefore, is known as a set-reset, or SR Latch. To create an SR Latch, we can wire two NOR gates in such a way that the output of one feeds back to the input of another, and vice versa, like this: The Q and not-Q outputs are supposed to be in opposite states.

  • SR latch is basically a sequential circuit and it is a type of unclocked flip flops and we know flip flops are used to store and tranfer 1 bit of data simillarly sr latch is used for this purpose rather it is used as a multivibrator whose value vibrates/oscillates between 1 and 0 means 2 stable states high or low so it is also used as bistable multivibrator 
    it has two outputs inverting and non inverting and they are level triggerd devices
    it is also used in 555 Timer IC and its advance version ic 556 which have two 555 Ic in it.

  • A latch is an example of a bistable multivibrator, that is, a device with exactly two stable states. ... As the name suggests, latches are used to "latch onto" information and hold in place. Latches are very similar to flip-flops, but are not synchronous devices, and do not operate on clock edges as flip-flops do.

  • SR latch is a bi stable single bit memory device, which is used in many sequential circuits for various memory applications like in bit wise registers and one more use in heavy electrical systems is in Debounce switch circuits, where the latch gives continuous pulses with miliseconds time period and the mechanical switches are replaced with digital circuits.

  • SR latch is used for keypad button like in our old mobile phones, when we press the button, then that particular button sorted with ground else all button are at there max voltage, then system sends the information that a button is pressed and works accordingly.
