Logic comparators, also known as binary comparators and digital comparators are semiconductor logic ICs (integrated circuits) that has been designed as a combinational circuit for the testing of values represented by one binary word.
Logic comparators test whether the value is greater than, less than, or equal to the value represented by another binary word. These devices are used commonly in digital logic circuit design and are also utilised in other key logic circuits.
There are two main types of logic comparators and they are;
Logic comparators are also offered with a variety of configurations such as Number of Bits configured on to the IC, varied maximum operating supply voltage and different output types such as push pull and TTL (Transistor–transistor logic)
These ICs have a range of application use such as;
