CPC7583
Line Card Access Switch
Description
The CPC7583 is a monolithic 10-pole line card access
switch in a 28-pin SOIC package. It provides the
necessary functions to replace three 2-Form-C
electromechanical relays on analog line cards and
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/ringing return, and test access. The
CPC7583 requires only a +5 V supply and offers
break-before-make or make-before-break switch
operation.
