Description
The CPC7592 is a member of Clare’s next generation
Line Card Access Switch family. This monolithic 6-pole
solid-state switch is available in either a 16-pin SOIC
or a 16-pin DFN 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
requires only a +5V supply for operation and
logic-level inputs for control.
The CPC7592 is very similar to the Clare CPC7582
with the addition of controlled start-up states and TTL
compatible logic inputs.
The CPC7592xC logic provides alternative test states
from the CPC7592xA/B and while also providing
greater protection SCR trigger and hold current
ratings.

Description
Absolute maximum electrical ratings are at 25°C.
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
