HC5503PRCRZ中文资料INTERSIL数据手册PDF规格书

The HC5503PRC 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.
