Balanced PBX/Key Sys tem SLIC,  
Subs criber Line Interface Circuit  
Features  
• Monolithic Integrated Device  
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.  
• Controlled Supply of Battery Feed Current for Short Loops  
(30mA)  
• Single +5V Supply  
• Allows Interfacing With All Ringing Systems  
• Switch Hook Detection  
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.  
• Compatible With Worldwide PBX Performance  
Requirements  
• Low Power Consumption During Standby  
• Pb-free Available  
Applications  
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.  
• PBX Switches (Analog, Digital or ISDN)  
• Key Telephone Systems (KTS)  
• ISDN PC Plug in Modems  
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).  
• ISDN Small Office/Home Office (SOHO) Terminal  
Adapters (TA)  
• CTI (Computer Telephony Integration) Products  
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.
