It provides the necessary functions to replace a 2-Form-C electromechanical relay on traditional analog and integrated voice and data IVD line cards found in central office, access, and PBX equipment. The CPC7581 contains solid-state switches for tip and ring lead line break and ringing injection/ringing return. The device requires only a +5 V supply and offers break-before-make and make-before-break operation using logic-level inputs. The CPC7581xA versions include an SCR that provides protection to the SLIC and subsequent circuitry during a fault condition. The CPC7581xC versions are functionally identical to the CPC7581xA versions, but with higher SCR hold current.
