CPC7581

DS-CPC7581-R2

The CPC7581 is a monolithic solid state switch in a 16 pin
surface mount SOIC package. It provides the necessary
functions to replace a 2-Form-C electromechanical relay
on analog line cards found in Central Office, Access and
PBX equipment. The device contains solid state switches
for tip and ring line break and ring injection/ring return.
The CPC7581 requires only a +5V supply and offers
“break-before-make” or “make-before-break” switch oper­ation using simple logic level input control. There are two
versions of the CPC7581, the CPC7581BA and the
CPC7581BB. The “BA” version has a protection SCR
which provides protection to the SLIC device and subse­quent circuitry during fault conditions.

• Central office (CO)

• Digital Loop Carrier (DLC)

• PBX Systems

• Digitally Added Main Line (DAML)

• Hybrid Fiber Coax (HFC)

• Fiber in the Loop (FITL)

• Pair Gain System

• Channel Banks

• Small 16 pin surface mount SOIC package

• Monolithic IC reliability

• Low matched RDS

ON

• Eliminates the need for zero cross switching

• Flexible switch timing to transition from ringing mode

to idle/talk mode

• Clean, bounce free switching

• Tertiary Protection consisting of integrated current

limiting, thermal shutdown and SLIC protection

• 5V operation with power consumption <10mW

• Intelligent battery monitor

• Latched logic level inputs, no drive circuitry

• Pin to pin compatible to the Lucent 7581 family

Absolute Maximum Ratings are stress ratings.
Functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this data sheet is not
implied. Exposure of the device to the absolute
maximum ratings for extended period may degrade
the device and effect its reliability.
