Unbalanced PBX/Key System SLIC,

Subscriber Line Interface Circuit

Features

• Monolithic Integrated Device

• Single +5V Supply

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.

• Controlled Supply of Battery Feed Current for Short Loops

(30mA)

• Allows Interfacing With All Ringing Systems

• Switch Hook Detection

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.

• Low Power Consumption During Standby

Applications

• PBX Switches (Analog, Digital or ISDN)

• Key Telephone Systems (KTS)

• ISDN PC Plug in Modems

• ISDN Small Ofﬁce/Home Ofﬁce (SOHO) Terminal Adapt-

ers (TA)

The HC5503C provides on-hook transmission and

• CTI (Computer Telephony Integration) Products

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.

Ordering Information

TEMP.

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.
