CPC7592 Line Card Access Switch INTEGRATED CIRCUITS DIVISION Features Description TTL logic level inputs for 3.3V logic interfaces The CPC7592 is a member of IXYS Integrated Smart logic for power up / hot plug state control Circuits Divisions next generation Line Card Access Monolithic IC reliability Switch family. This monolithic 6-pole solid-state switch Low matched R is available in a 16-pin SOIC package. It provides the ON necessary functions to replace two 2-Form-C Eliminates the need for zero cross switching electro-mechanical relays used on traditional analog Flexible switch timing to transition from ringing mode and contemporary integrated voice and data (IVD) line to talk mode. cards found in Central Office, Access, and PBX Clean, bounce-free switching equipment. Because this device contains solid state Tertiary protection consisting of integrated current switches for tip and ring line break, ringing limiting, voltage clamping, and thermal shutdown for injection/return, and test access, it needs only a +5V SLIC protection supply for operation and logic-level inputs for control. 5V operation with power consumption < 10 mW Intelligent battery monitor The CPC7592 is very similar to the CPC7582 with the Latched logic-level inputs, no external drive circuitry addition of controlled start-up states and TTL required compatible logic inputs. Small 16-pin SOIC Package The CPC7592BC logic provides alternative test states from the CPC7592BA/BB while also providing greater Applications protection SCR trigger and hold current ratings.
