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 DFN 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 TTL 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.
For negative transient voltage protection the
CPC7591xA versions include SCRs to provide voltage
fold-back protection for the SLIC and subsequent
circuitry, while the CPC7591xB versions utilize
clamping diodes to the VBAT pin. For positive transient
voltage protection all versions provide clamping
diodes to the FGND pin.
