Description

The CPC7593 is a member of IXYS Integrated

Circuits Division’s next generation Line Card Access

Switch (LCAS) family. This monolithic 10-pole line

card access switch is available in 20-pin and 28-pin

SOIC packages. 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.
