Unbalanced Pbx/key System Slic, Subscriber Line Interface Circuit Corporation

The Intersil HC5503C is a low cost Subscriber Line Interface Circuit (SLIC), that replaces the components of an unbalanced Discrete Analog circuit design. The monolithic integrated design provides improved performance and system reliability. The SLIC provides: Current Limited DC feed to the subscriber loop, maintains a at frequency response over the voice band and beyond, has self resetting thermal protection that allows conversation to continue while the fault is present, provides a TTL subscriber off-hook indication even in the presence of longitudinal currents, provides unbalanced 2-wire transmission while maintaining an excellent longitudinal balance and limits system power consumption on short loops. The HC5503C provides on-hook transmission and longitudinal current rejection in both the on-hook or off-hook conditions. The SLIC needs only one +5V supply in addition to the main battery supply (-24V to -58V) for loop current. Available in 22PDIP and 24SO packaging. The HC5503C is ideally suited as a replacement for Discrete line circuits in low cost Analog PABXs, Small Ofce/Home Ofce products or Small Key Systems. By Intersil Corporation
