Balanced PBX/Key System SLIC,

Subscriber 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

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

• ISDN Small Ofﬁce / Home Ofﬁce (SOHO) Terminal

Adapters (TA)

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).

• CTI (Computer Telephony Integration) Products

Available in 22PDIP AND 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.
