Buffers / DriversBuffers and drivers are types of logic ICs that are used to amplify or boost the strength of a digital signal. Buffers are used to isolate one circuit from another, and to prevent the loading effect, where one circuit affects the operation of another. Drivers, on the other hand, are used to increase the current or voltage of a digital signal, in order to drive a load, such as a motor or a display. Both buffers and drivers are commonly used in digital electronics to improve the performance and reliability of circuits and systems.
