EIA/ITU 24V PABX SLIC with 25mA
Loop Feed
The HC-5524 telephone Subscriber Line Interface Circuit
integrates most of the BORSCHT functions on a monolithic
IC. The device is manufactured in a Dielectric Isolation (DI)
process and is designed for use as a 24V interface between
the traditional telephone subscriber pair (Tip and Ring) and
the low voltage filtering and coding/decoding functions of the
line card. Together with a secondary protection diode bridge,
the device will withstand 500V induced surges, in plastic
packages. The SLIC also maintains specified transmission
performance in the presence of externally induced
longitudinal currents. The BORSCHT functions that the SLIC
provides are:
• Battery Feed with Subscriber Loop Current Limiting
• Overvoltage Protection
• Ring Relay Driver
• Supervisory Signaling Functions
• Hybrid Functions (with External Op-Amp)
• Test (or Battery Reversal) Relay Driver
In addition, the SLIC provides selective denial of power to
subscriber loops, a programmable subscriber loop current
limit from 20mA to 60mA, a thermal shutdown with an alarm
output and line fault protection. Switch hook detection, ring
trip detection and ground key detection functions are also
incorporated in the SLIC device.
The HC-5524 SLIC is ideally suited for line card designs in
PBX and DLC systems, replacing traditional transformer
solutions.

SYMBOL
DESCRIPTION
AG Analog Ground - To be connected to zero potential. Serves as a reference for the transmit output and receive
(Note 4) input terminals.
VB+ Positive Voltage Source - Most Positive Supply.
C1 Capacitor #C1 - An external capacitor to be connected between this terminal and analog ground. Required for
proper operation of the loop current limiting function.
F1 Function Address #1 - A TTL and CMOS compatible input used with F0 function address line to externally se-
lect logic functions. The three selectable functions are mutually exclusive. See Truth Table on front page. F1
should be toggled high after power is applied.
F0 Function Address #0 - A TTL and CMOS compatible input used with F1 function address line to externally se-
lect logic functions. The three selectable functions are mutually exclusive. See Truth Table on front page.
6 10
RS Ring Synchronization Input - A TTL - compatible clock input. The clock is arranged such that a positive pulse
(50µs - 500µs) occurs on the zero crossing of the ring voltage source, as it appears at the RFS terminal. For
Tip side injected systems, the RS pulse should occur on the negative going zero crossing and for Ring injected
systems, on the positive going zero crossing. This ensures that the ring delay activates and deactivates when
the instantaneous ring voltage is near zero. If synchronization is not required, the pin should be tied to +5V.
7 11 SHD Switch Hook Detection - An active low LS TTL compatible logic output. A line supervisory output.
8 12 GKD Ground Key Detection - An active low LS TTL compatible logic output. A line supervisory output.
9 13 TST A TTL logic input. A low on this pin will set a latch and keep the SLIC in a power down mode until the proper
F1, F0 state is set and will keep ALM low. See Truth Table on front page.
10 17
ALM
A LS TTL compatible active low output which responds to the thermal detector circuit when a safe operating
die temperature has been exceeded. When TST is forced low by an external control signal, ALM is latched low
until the proper F1, F0 state and TST input is brought high. The ALM can be tied directly to the TST pin to
power down the part when a thermal fault is detected and then reset with F0, F1. See Truth Table on front page.
It is possible to ignore transient thermal overload conditions in the SLIC by delaying the response to the TST
pin from the ALM. Care must be exercised in attempting this as continued thermal overstress may reduce com-
ponent life.
11 18 ILIMIT Loop Current Limit - Voltage on this pin sets the short loop current limiting conditions using a resistive voltage
divider.
12 19 OUT1 The analog output of the spare operational amplifier.
13 20
-IN1 The inverting analog input of the spare operational amplifier.
