Description
The CPC7595 is a member of Clare’s next generation
Line Card Access Switch (LCAS) family. This
monolithic 10-pole line card access switch is available
in a 20 or 28 pin SOIC or a 28 pin DFN package. It
provides the necessary functions to replace three
2-Form-C electromechanical relays on analog line
cards or combined voice and data line cards found in
central office, access, and PBX equipment. The
device contains solid state switches for tip and ring line
break, ringing injection and test access. The CPC7595
requires only a +5 V supply and provides stable start
up conditioning during system power up and for hot
plug insertion. Once active, the inputs respond to
traditional TTL logic levels enabling the CPC7595 to
be used with 3.3V only logic.
Applications
Standard voice linecards
Integrated Voice and Data (IVD) linecards
Central office (CO)
Digital Loop Carrier (DLC)
PBX Systems
Digitally Added Main Line (DAML)
Fiber in the Loop (FITL)

Ordering Information
For delivery in tubes, specify CPC7595Zx for the 20
pin SOIC (38/tube), CPC7595Bx for the 28 pin SOIC
(27/tube), or CPC7595Mx for the DFN (33/tube). For
tape and reel delivery, add “TR”, without quotes, to the
part number. SOIC: 20 or 28 pin (500/reel), DFN
(1000/reel).
