HC-5502B
EIA/ITU PABX SLIC with 30mA Loop Feed
The Intersil SLIC incorporates many of the BORSHT
functions on a single IC chip. This includes DC battery feed,
a ring relay driver, supervisory and hybrid functions. This
device is designed to maintain transmission performance in
the presence of externally induced longitudinal currents.
Using the unique Intersil dielectric isolation process, the
SLIC can operate directly with a wide range of station
battery voltages.
The SLIC also provides selective denial of power. If the PBX
system becomes overloaded during an emergency, the SLIC
will provide system protection by denying power to selected
subscriber loops.
The Intersil SLIC is ideally suited for the design of new digital
PBX systems, by eliminating bulky hybrid transformers.

DESCRIPTION
2
1
TIP
An analog input connected to the TIP (more positive) side of the subscriber loop through a 150
feed resistor and a ring relay contact. Functions with the Ring terminal to receive voice signals from
the telephone and for loop monitoring process.
3
2
RING
An analog input connected to the RING (more negative) side of the subscriber loop through a 150
feed resistor and a ring relay contact. Functions with the Tip terminal to receive voice signals from
the telephone and for loop monitoring purposes.

Positive Voltage Source - Most positive supply. V
B

5

C
1
Capacitor #1 - Optional Capacitor used to improve power supply rejection. This pin should be left open
if unused.
6
5
C
3
Capacitor #3 - An external capacitor to be connected between this terminal and analog ground. Re-
quired for proper operation of the loop current limiting function, and for filtering V
B
- supply. Typical
value is 0.3
F, 30V.
7
6
DG
(Note 5)
Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and
outputs on the SLIC.
9
7
RS
Ring Synchronization Input - A TTL - compatible clock input. The clock should be arranged such that
a positive transition occurs on the negative going zero crossing of the ring voltage source, ensuring
that the ring relay is activated and deactivated when the instantaneous ring voltage is near zero. If
synchronization is not required, tie to 5V.
10
8
RD
Relay Driver - A low active open collector logic output. When enabled, the external ring relay is
energized.
11
9
TF
Tip Feed - A low impedance analog output connected to the TIP terminal through a 150
feed
resistor. Functions with the RF terminal to provide loop current, feed voice signals to the telephone
set, and sink longitudinal current.
12
10
RF
Ring Feed - A low impedance analog output connected to the RING terminal through a 150
feed
resistor. Functions with the TF terminal to provide loop current, feed voice signal to the telephone
set, and sink longitudinal current.
13
11
V
B
-
Negative Voltage Source - Most negative supply. V
B
- is typically -48V with an operational range of -
42V to -58V. Frequently referred to as "battery".
14
12
BG
(Note 1)
Battery Ground - To be connected to zero potential. All loop current and some quiescent current
flows into this ground terminal.
16
13
SHD
Switch Hook Detection - A low active LS TTL - compatible logic output. This output is enabled for
loop currents exceeding 10mA and disabled for loop currents less than 5mA.
17
14
GKD
Ground Key Detection - A low active LS TTL - compatible logic output. This output is enabled if the
DC current into the ring lead exceeds the DC current out of the tip lead by more than 20mA, and
disabled if this current difference is less than 10mA.
18
15
PD
Power Denial - A low active TTL - Compatible logic input. When enabled the switch hook detect
(SHD) and ground key detect (GKD) are not necessarily valid, and the relay driver (RD) output is
disabled.
19
16
RC
Ring Command - A low active TTL - Compatible logic input. When enabled, the relay driver (RD)
output goes low on the next rising edge of the ring sync (RS) input, as long as the SLIC is not in the
power denial state (PD = 0) or the subscriber is not already off- hook (SHD = 0).
20
17
C
2
Capacitor #2 - An external capacitor to be connected between this terminal and digital ground.
Prevents false ground key indications from occurring during ring trip detection. Typical value is
0.15
F, 10V. This capacitor is not used if ground key function is not required.
