Digital ComparatorsA digital comparator is a type of logic IC that compares two digital inputs and produces a digital output based on the result of the comparison. For example, a digital comparator might compare two binary numbers and output a 1 if the first number is greater than the second number, or a 0 if the first number is less than or equal to the second number. Digital comparators are commonly used in digital circuits to perform a variety of functions, such as comparing numbers, detecting transitions, and performing arithmetic operations.
