HC5503T
Balanced PBX / Key System SLIC,
Subscriber Line Interface Circuit
The Intersil HC5503T is a low cost Subscriber Line Interface
Circuit (SLIC) that replaces the components of a discrete
Transformer Analog circuit design. The monolithic integrated
design provides improved performance and system
reliability.
The HC5503T 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, and limits
system power consumption on short loops.
The HC5503T provides balanced 2-wire transmission and
has excellent longitudinal balance, while providing 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 for loop current and operates over a range of
battery voltages (-24V to -58V).
Available in 24SO packaging. The HC5503T is ideally suited
as a replacement for discrete line circuits in low cost analog
PABXs, small Office/Home Office products or Small Key
Systems.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
