Description
The CPC7581 is a monolithic solid-state four-pole
switch in a 16-pin package. It provides the necessary
functions to replace a 2-Form-C electromechanical
relay on traditional analog and integrated voice and
data (IVD) line cards found in central office, access, and
PBX equipment. The CPC7581 contains solid-state
switches for tip and ring lead line break and ringing
injection/ringing return. The device requires only a +5 V
supply and offers break-before-make and
make-before-break operation using logic-level inputs.
The CPC7581xA versions include an SCR that
provides protection to the SLIC and subsequent
circuitry during a fault condition. The CPC7581xC
versions are functionally identical to the CPC7581xA
versions, but with higher SCR hold current.
