This monolithic 10-pole line card access switch is available in 20-pin and 28-pin SOIC packages. 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 CPC7593 requires only a +5 V supply and provides stable start up conditioning during system power up and for hot plug insertion applications. Once active, the inputs respond to traditional TTL logic levels enabling the CPC7593 to be used with 3.3V only logic.
