CPC7591

Description

The CPC7591 is a member of IXYS Integrated

Circuits Division’s next 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

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

CPC7591BA version includes SCRs to provide

voltage fold-back protection for the SLIC and

subsequent circuitry, while the CPC7591BB version

utilizes clamping diodes to the V

BAT

pin. For positive

transient voltage protection all versions provide

clamping diodes to the F

GND

pin.
