Description
The CPC7691 is a member of Clare’s third-generation
Line Card Access Switch (LCAS) family. This
monolithic 4-pole solid state switch is available in a
16-pin SOIC 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 CPC7691 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 CPC7691 to be used with 3.3V-only logic.
For negative transient voltage protection the
CPC7691BA version includes SCRs to provide
voltage fold-back protection for the SLIC and
subsequent circuitry, while the CPC7691BB version
utilizes clamping diodes to the VBAT pin. For positive
transient voltage protection all versions provide
clamping diodes to the FGND pin.
