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.
