![]() ![]() This is just one way to implement a latch using NOT, NAND, and NOR gates. > When S is 0 and R is 1, the latch is reset (the Q output is 0 and the Q' output is > When both S and R are 0, the latch maintains its current state (either set or reset). > When S is 1 and R is 0, the latch is set (the Q output is 1 and the Q' output is 0). The output of the first NAND gate is connected to the Q output, and the output of the second NAND gate is connected to the Q' output. The Q' output is connected to a second NAND gate along with the R input. The S input is connected to a NAND gate along with the Q output. Using these gates, we can implement a latch as follows: ![]() It performs a NOT-OR operation, meaning that the output is 1 if all of the inputs are 0, and 0 if any of the inputs are 1. The NOR gate also has two or more inputs and a single output. It performs a NOT-AND operation, meaning that the output is 1 if any of the inputs are 0, and 0 if all of the inputs are 1. The NAND gate has two or more inputs and a single output. It inverts the value at the input, so if the input is 1, the output is 0, and if the input is 0, the output is 1. The NOT gate has a single input and a single output. Here is an example of how a latch can be implemented using NOT, NAND, and NOR gates: The outputs are the stored values, and the inputs are used to control the stored values.Ī latch can be implemented using a variety of different gates, such as NOT gates, NAND gates, and NOR gates. It consists of two inputs (S and R) and two outputs (Q and Q'). A latch is a type of digital circuit that is used to store and maintain a binary value (either 0 or 1). ![]()
