CPC7581BCTR [IXYS]

The CPC7581 is a monolithic solid-state four-pole switch available in 16-pin SOIC or DFN packages. The DFN package footprint is 60% smaller than the SOIC version. It replaces electromechanical relays in analog and integrated voice/data line cards for central office, access, and PBX equipment. The device contains solid-state switches for tip/ring lead break and ringing injection/return, requiring only a +5V supply. It offers break-before-make and make-before-break operation with logic-level inputs. Key features include low matched R ON, elimination of zero-cross switching, flexible switch timing, clean bounce-free switching, tertiary protection (integrated current limiting and thermal shutdown for SLIC protection), <10mW power consumption, intelligent battery monitoring, and latched logic-level inputs. The CPC7581xA versions include an SCR for fault protection, while CPC7581xC versions have higher SCR hold current.
