Description

The CPC7592 is a member of IXYS Integrated

Circuits Division’s next generation Line Card Access

Switch family. This monolithic 6-pole solid-state switch

is available in a 16-pin SOIC package. It provides the

necessary functions to replace two 2-Form-C

electro-mechanical relays used on traditional analog

and contemporary integrated voice and data (IVD) line

cards found in Central Office, Access, and PBX

equipment. Because this device contains solid state

switches for tip and ring line break, ringing

injection/return, and test access, it needs only a +5V

supply for operation and logic-level inputs for control.

The CPC7592 is very similar to the CPC7582 with the

addition of controlled start-up states and TTL

compatible logic inputs.

The CPC7592BC logic provides alternative test states

from the CPC7592BA/BB while also providing greater

protection SCR trigger and hold current ratings.
