Low Cost SLIC For Large Telecom
Switches
The HC5503PRI is a low cost SLIC optimized for large
Telecom switches. It combines a flexible voltage feed
architecture with the Intersil latch-free DI bonded wafer
process, to provide a low component count, carrier class
solution at very low cost. The re-configurable design permits
simple, economical solutions for campus-wide call center
and PBX applications. External components can be used in
conjunction with the high battery voltage capability to meet
the complex impedance and long loop drive requirements of
Central Office switches, worldwide.
