Harris Semiconductor, a division of Harris Corporation, was founded in 1960 and headquartered in Melbourne, Florida, USA. It was a pioneer in analog and mixed-signal integrated circuits. The product portfolio included operational amplifiers, data converters, power management ICs, and interface products. Notable product lines were the HA- series op amps, HI- series high-speed converters, and the CD4000 series CMOS logic. The company held a strong position in military and aerospace electronics with radiation-hardened components. In 1999, Harris spun off its semiconductor business, which was acquired by Intersil Corporation and later became part of Renesas Electronics. At its peak, Harris Semiconductor was recognized for advanced bipolar and CMOS technologies. Its products found use in industrial, communication, and defense applications. The company contributed significantly to the evolution of analog integrated circuit design.
