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.
