Description
The CPC7583 is a monolithic 10-pole line card access
switch in a 20- or 28-pin SOIC or a 28-pin DFN
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.
