Logic - Comparators

Category Introduction

Products in the logic comparator family are used to generate an output based on comparison of information represented in a digital format; identity types indicate whether or not two inputs are identical, magnitude types also indicate which of the two inputs is greater when they are not identical. They are distinct from devices that compare the magnitude of two analog inputs, which are known as linear comparators and are catalogued separately.
