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
page 12 for more information. The CPC7582xC also
has a higher trigger and hold current for the protection
SCR.
