Unbalanced PBX/Key System SLIC,
Subscriber Line Interface Circuit
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 flat 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 PABX’s, Small Office/Home Office products
or Small Key Systems.
