8542.33.00.01 - Amplifiers

This HTS category, 8542.33.00, specifically classifies electronic integrated circuits that function as amplifiers. These are semiconductor devices designed to increase the amplitude or power of an electrical signal. The core function here is signal amplification, distinguishing them from other integrated circuits based on their primary purpose of boosting signal strength.

When classifying, it is crucial to differentiate these amplifiers from their sibling categories. Processors and controllers (8542.31.00) are designed for executing instructions and managing data flow, while memories (8542.32.00) are dedicated to storing information. The "Other" category (8542.39.00) serves as a residual for integrated circuits not fitting the specific definitions of processors, controllers, memories, or amplifiers. Therefore, the key differentiator for 8542.33.00 is the inherent and primary function of signal amplification within the integrated circuit's design.

As this is a leaf node, there are no further subdivisions under this specific HTS code. Classification under 8542.33.00 is determined by the integrated circuit's designed function to amplify electronic signals. This includes a wide array of semiconductor devices used in audio systems, radio frequency applications, operational amplifiers, and various signal processing circuits where signal magnitude enhancement is the primary operational characteristic.
