1 / 17 page  DS-CPC7581-R05 www.clare.com 1 Features • Small 16-pin SOIC or DFN package • DFN package printed-circuit board footprint is 60 percent smaller than the SOIC version, 40 percent smaller than fourth generation EMR solutions. • Monolithic IC reliability • Low, matched R ON • Eliminates the need for zero-cross switching • Flexible switch timing for transition from ringing mode to idle/talk mode. • Clean, bounce-free switching • Tertiary protection consisting of integrated current limiting, thermal shutdown for SLIC protection • 5 V operation with power consumption < 10 mW • Intelligent battery monitor • Latched logic-level inputs, no external drive circuitry required • SOIC package pin-compatible with Legerity product Applications • Central office (CO) • Digital Loop Carrier (DLC) • PBX Systems • Digitally Added Main Line (DAML) • Hybrid Fiber Coax (HFC) • Fiber in the Loop (FITL) • Pair Gain System • Channel Banks Description The CPC7581 is a monolithic solid-state four-pole switch in a 16-pin package. 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. Ordering Information Figure 1.
