EIA/ITU PABX SLIC with 40mA 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
1 TIP An analog input connected to the TIP (more positive) side of the subscriber loop through a 150feed re-
sistor and a ring relay contact. Functions with the Ring terminal to receive voice signals from the telephone
and for loop monitoring purposes.
2 RING An analog input connected to the RING (more negative) side of the subscriber loop through a 150feed
resistor and a ring relay contact. Functions with the Tip terminal to receive voice signals from the telephone
and for loop monitoring purposes.
3 RFS Senses ring side of loop for ground key and ring trip detection. During ringing, the ring signal is inserted
into the line at this node and RF is isolated from RFS via a relay.
4 VB+ Positive Voltage Source - Most positive supply. VB+ is typically 12V or 5V.
5 C3 Capacitor #3 - An external capacitor to be connected between this terminal and analog ground. Required
for proper operation of the loop current limiting function, and for filtering VB-. Typical value is 0.3µF, 30V.
6 DG Digital Ground - To be connected to zero potential and serves as a reference for all digital inputs and out-
(Note 5) puts on the SLIC microcircuit.
7 RS Ring Synchronization Input - A TTL-compatible clock input. The clock should be arranged such that a pos-
itive pulse transition occurs on the zero crossing of the ring voltage source, as it appears at the RFS termi-
nal. 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 relay activates and
deactivates when the instantaneous ring voltage is near zero. If synchronization is not required, the pin
should be tied to 5V.
8 RD Relay Driver - A low active open collector logic output. When enabled, the external ring relay is energized.
9 TF Tip Feed - A low impedance analog output connected to the TIP terminal through a 150feed resistor.
Functions with the RF terminal to provide loop current, feed voice signals to the telephone set, and sink
longitudinal current.
10 RF Ring Feed - A low impedance analog output connected to the RING terminal through a 150feed resistor.
Functions with the TF terminal to provide loop current, feed voice signals to the telephone set, and sink
longitudinal current.
11 VB- Negative Voltage Source - Most negative supply. VB- is typically -48V with an operational range of -42V to
-58V. Frequently referred to as “battery”.
12 BG Battery Ground - To be connected to zero potential. All loop current and some quiescent current flows into
(Note 5) this ground terminal.
13 SHD Switch Hook Detection - A low active LS TTL - compatible logic output. This output is enabled for loop cur-
rents exceeding 10mA and disabled for loop currents less than 5mA.
14 GKD Ground Key Detection - A low active LS TTL - compatible logic output. This output is enabled if the DC cur-
rent 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.
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.
16 RC Ring Command - A low active TTL - Compatible logic input. When enabled, the relay driver (RD) output
goes low on the next high level 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).
17 C2 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 0.15µF, 10V. This ca-
pacitor is not used if ground key function is not required and (Pin 17) may be left open or connected to digital
ground.
18 OUT The analog output of the spare operational amplifier. The output voltage swing is typically ±5V.
19 -IN The inverting analog input of the spare operational amplifier.
