1. Absolute maximum ratings are limiting values, applied individually, beyond which the serviceability of the circuit may be impaired. Func-
tional operability under any of these conditions is not necessarily implied.
2. May Be Extended to 1900Ω With Application Circuit.
3. These parameters are controlled by design or process parameters and are not directly tested. These parameters are characterized upon
initial design release, upon design changes which would affect these characteristics, and at intervals to assure product quality and spec-
ification compliance.

DESCRIPTION
Analog Ground - To be connected to zero potential. Serves as a reference for the transmit output
and receive input terminals.
Positive Voltage Source - Most Positive Supply.
Capacitor #C1 - An external capacitor to be connected between this terminal and analog ground.
Required for proper operation of the loop current limiting function.
Function Address #1 - A TTL and CMOS compatible input used with F0 function address line to
externally select logic functions. The three selectable functions are mutually exclusive. See Truth
Table on page1. F1 should be toggled high after power is applied.

DESCRIPTION
Function Address #0 - A TTL and CMOS compatible input used with F1 function address line to
externally select logic functions. The three selectable functions are mutually exclusive. See Truth
Table on page 1.
Ring Synchronization Input - A TTL - compatible clock input. The clock is arranged such that a
positive pulse (50 - 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 en-
sures 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 +5.
Switch Hook Detection - An active low LS TTL compatible logic output. A line supervisory output.
Ground Key Detection - An active low LS TTL compatible logic output. A line supervisory output.
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 page 1.
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 page 1. It is possible to ignore transient thermal over-
load 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 reduced component life.
Loop Current Limit - Voltage on this pin sets the short loop current limiting conditions using a re-
sistive voltage divider.
The analog output of the spare operational amplifier.
The inverting analog input of the spare operational amplifier.
An analog input connected to the TIP (more positive) side of the subscriber loop through a feed
resistor and ring relay contact. Functions with the RING terminal to receive voice signals from
the telephone and for loop monitoring purpose.
An analog input connected to the RING (more negative) side of the subscriber loop through a
feed resistor. Functions with the TIP terminal to receive voice signals from the telephone and for
loop monitoring purposes.
Ring Feed Sense - Senses RING side of the loop for Ground Key Detection. During Ring injected
ringing the ring signal at this node is isolated from RF via the ring relay. For Tip injected ringing,
the RF and RFS pins must be shorted.
Receive Input, Four Wire Side - A high impedance analog input. AC signals appearing at this in-
put drive the Tip Feed and Ring Feed amplifiers differentially.
Longitudinal Amplifier Output - A low impedance output to be connected to C2 through a low pass
filter. Output is proportional to the difference in I
TIP
and I
RING
.
Transmit Output, Four Wire Side - A low impedance analog output which represents the differ-
ential voltage across TIP and RING. Transhybrid balancing must be performed beyond this out-
put to completely implement two to four wire conversion. This output is referenced to analog
ground. Since the D.C. level of this output varies with loop current, capacitive coupling to the next
stage is necessary.
A TTL compatible input used to control PR. PRI active High = PR active low.
An active low open collector output. Can be used to drive a Polarity Reversal Relay.
Digital Ground - To be connected to zero potential - serves as reference for all digital inputs and
outputs on the SLIC.
Battery Ground - Tube connected to zero potential. All loop current and some quiescent current
