CPC7583
Line Card Access Switch
Features
Description
• Small 28 pin surface mount SOIC package
The CPC7583 is a monolithic solid state switch in a 28 pin
surface mount SOIC package. It provides the necessary
functions to replace three 2-Form-C electromechanical re-
lays on analog line cards found in Central Office, Access
and PBX equipment. The device contains solid state
switches for tip and ring line break, ring injection/ring re-
turn, line test access, test in access and ringing generator
testing. The CPC7583 requires only a +5V supply and of-
fers “break-before-make” or “make-before-break” switch
operation using simple logic level input control. The
CPC7583 has 4 versions. The CPC7583BA and the
CPC7583BC contain the integrated protection SCR while
the CPC7583BC and the CPC7583BD contain an extra
logic state which is detailed in later sections.
• Monolithic IC reliability
• Low matched RDSON

idle/talk mode
• Clean, bounce free switching
• Tertiary protection consisting of integrated current
limiting, thermal shutdown and SLIC protection
• 5V operation with power consumption <10mW
• Intelligent battery monitor
• Latched logic level inputs, no drive circuitry
