Description
The CPC7595 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 a 20-pin or 28-pin
SOIC package 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 +5V 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.
