Description
The CPC7593 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 MLP 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 CPC7593
requires only a +5 V supply and provides stable start
up conditioning during system power up and for hot
plug insertion applications. Once active, the inputs
respond to traditional TTL logic levels enabling the
CPC7593 to be used with 3.3V only logic.
Ordering Information
For delivery in tubes, specify CPC7593Zx for the 20
pin SOIC (38/tube), CPC7593Bx for the 28 pin SOIC
(27/tube), or CPC7593Mx for the MLP (54/tube). For
tape and reel delivery, add “TR”, sans quotes to the
part number. SOIC: 20 or 28 pin (500/reel), MLP
(1000/reel).
