CPC7581 Datasheet | Clare

Features - Small 16 pin surface mount SOIC package - Monolithic IC reliability - Low matched RDSON - Eliminates the need for zero cross switching - Flexible switch timing to transition from ringing mode to idle/talk mode - Clean, bounce free switching - Tertiary Protection consisting of integrated current limiting, thermal shutdown and SLIC protection - 5V operation with power consumption <10m W - Intelligent battery monitor - Latched logic level inputs, no drive circuitry - Pin to pin patible to the Lucent 7581 family 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 switch in a 16 pin surface mount SOIC package. It provides the necessary functions to replace a 2-Form-C electromechanical relay on analog line cards found in Central Office, Access and PBX equipment. The device contains solid state switches for tip and ring line break and ring injection/ring return. The CPC7581 requires only a +5V supply and offers “break-before-make” or “make-before-break” switch operation using simple logic level input control. There are two versions of the CPC7581, the CPC7581BA and the CPC7581BB. The “BA” version has a protection SCR which provides protection to the SLIC device and subsequent circuitry during fault conditions.
