Clare, Inc. was founded in 1966 and is headquartered in Beverly, Massachusetts, USA. It is a pioneering semiconductor company specializing in high-voltage analog and mixed-signal integrated circuits. The company’s core product areas include solid state relays (SSRs), high-voltage analog switches, and optical isolation components. Notable product families include the CPC series of solid state relays, the LITELINK data access arrangement ICs for telecom, and the CPC7701 high-voltage analog switch arrays. Clare’s proprietary BCDMOS process technology enables high integration and reliability in demanding high-voltage applications. Its products are widely used in telecommunications, industrial automation, medical instruments, and test equipment. Clare has also been a key supplier of optocouplers and isolated gate drivers for power management. In 2002, Clare, Inc. was acquired by IXYS Corporation, expanding its reach in power and mixed-signal semiconductors. Following Littelfuse, Inc.’s acquisition of IXYS in 2018, the Clare brand now serves as a product line within Littelfuse’s semiconductor portfolio. Despite the transition, Clare’s technology remains trusted for robust isolation and high-voltage solutions globally.
