Latches in Digital Logic

Latch is a digital circuit which converts its output according to its inputs instantly. To implement latches, we use different logic gates. In this article, we will see the definition of latches, latch types like SR, gated SR, D, gated D, JK and T with its truth table and diagrams and advantages and disadvantages of latch.

What are Latches?

Latches are digital circuits that store a single bit of information and hold its value until it is updated by new input signals. They are used in digital systems as temporary storage elements to store binary information. Latches can be implemented using various digital logic gates, such as AND, OR, NOT, NAND, and NOR gates....

Types of Latches in Digital Electronics

In digital electronics different types of latches are:...

SR Latch

S-R latches i.e., Set-Reset latches are the simplest form of latches and are implemented using two inputs: S (Set) and R (Reset). The S input sets the output to 1, while the R input resets the output to 0. When both S and R inputs are at 1, the latch is said to be in an “undefined” state. They are also known as preset and clear states. The SR latch forms the basic building blocks of all other types of flip-flops....

Gated SR Latch

A Gated SR latch is a SR latch with enable input which works when enable is 1 and retain the previous state when enable is 0....

D Latch

D latches are also known as transparent latches and are implemented using two inputs: D (Data) and a clock signal. The output of the latch follows the input at the D terminal as long as the clock signal is high. When the clock signal goes low, the output of the latch is stored and held until the next rising edge of the clock....

Gated D Latch

D latch is similar to SR latch with some modifications made. Here, the inputs are complements of each other. The D latch stands for “data latch” as this latch stores single bit temporarily....

JK Latch

JK latch has two inputs J and K. The output gets toggled when the J and K inputs are high. JK latch is just like SR latch, but it eliminates the undefined state of SR latch....

T Latch

When the JK inputs of JK latch are shorted we get the T latch. In T latch the outputs are toggled when the inputs are high....

Advantages of Latches

Some of the advantages of latches are listed below....

Disadvantages of Latches

Some of the disadvantages of latches are listed below....

Conclusion

We can conclude that latches are the mostly used in digital circuits for various purposes. Latches changes its output quickly with respect to new input. Different kinds of latches include SR latch, gated latch, D latch, gated D latch, JK latch and T latch....
