Digital integrated circuits (ICs) are semiconductor devices designed to process and store binary information—represented as 0s and 1s. These ICs include logic gates, microprocessors, microcontrollers, memory chips, counters, and digital signal processors (DSPs). Digital ICs operate using discrete voltage levels and are essential in computing, automation, communication, and consumer electronics. Known for their speed, reliability, and scalability, they enable complex tasks such as data processing, control operations, and system interfacing. With low power consumption and high integration density, digital ICs form the core of modern digital systems across virtually all technology sectors.
