This monolithic 10-pole line card access switch is available in a 20-pin or 28-pin SOIC package. It provides the necessary functions to replace three 2-Form-C electromechanical relays on analog line cards or combined voice and data line cards found in central office, access, and PBX equipment. The device contains solid state switches for tip and ring line break, ringing injection, and test access. The CPC7695 requires only a +5V supply and provides stable start-up conditioning during system power-up and for hot-plug insertion. Once active, the inputs respond to traditional TTL logic levels, enabling the CPC7695 to be used with 3.3V-only logic.
