Description
The CPC7582 is a monolithic solid-state switch in a
16-pin SOIC or DFN surface-mount package. It
provides the necessary functions to replace two
2-Form-C electro-mechanical relays on traditional
analog and integrated voice and data (IVD) 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 CPC7582 requires only a +5V supply and
offers break-before-make or make-before-break switch
operation using simple logic-level input control.
The CPC7582xC logic states differ from the
CPC7582xA/B. See “Functional Description” on
page 12 for more information. The CPC7582xC also
has a higher trigger and hold current for the protection
SCR.

Unless otherwise specified, minimum and maximum
values are production testing requirements.
Typical values are characteristic of the device at 25°C
and are the result of engineering evaluations. They are

1.4 ESD Rating
ESD Rating (Human Body Model)
1000 V
Absolute maximum electrical ratings are at 25°C.
Absolute maximum ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings for
an extended period may degrade the device and affect its
reliability.
