Description
The CPC7591 is a member of Clare’s next generation
Line Card Access Switch (LCAS) family. This
monolithic 4-pole solid state switch is available in
either a 16-pin SOIC or a 16-pin MLP package. It
provides the necessary functions to replace the
2-Form-C electromechanical ringing relay and it’s
associated snubber circuitry on traditional analog line
cards or contemporary integrated voice and data (IVD)
line cards found in Central Office (CO), Access and
PBX equipment. Because this device contains solid
state switches for tip and ring line break and for ringing
injection/return it requires only a +5 V supply for
operation and logic-level inputs for control. The
CPC7591 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 CPC7591 to
be used with 3.3V only logic.
The CPC7591 is very similar to Clare’s CPC7581 with
the addition of defined start-up states and TTL
compatible logic inputs.
CPC7591xA and CPC7591xC versions include an
SCR that provides protection to the SLIC and
subsequent circuitry during a fault condition. The
CPC7591xC versions have a higher SCR hold current.
The CPC7591xB versions utilize clamping diodes to
the VBAT pin to guard against negative fault transients.
Ordering Information
Specify CPC7591Bx for the SOIC package (47/tube)
and CPC7591Mx for the MLP (94/tube). Add “TR”,
sans quotes, to the part number for tape and reel
packaging. SOIC: 1000/reel or MLP: 2000/reel.
