SYMBOL
DESCRIPTION
1
RING
SENSE
Internally connected to output of RING power amplifier.
2
BGND
Battery Ground - To be connected to zero potential. All loop current and longitudinal current flow from this ground.
Internally separate from AGND but it is recommended that it is connected to the same potential as AGND.
4
V
CC
+5V power supply.
5
RINGRLY
Ring relay driver output.
6
V
BAT
Battery supply voltage, -24V to -56V.
7
R
SG
Saturation guard programming resistor pin.
8
NC
This pin is used during manufacturing. This pin is to be left open for proper SLIC operation.
9
E0
TTL compatible logic input. Enables the DET output when set to logic level zero and disables DET output when set to
a logic level one.
11
DET
Detector output. TTL compatible logic output. A zero logic level indicates that the selected detector was triggered (see
Truth Table for selection of Ground Key detector, Loop Current detector or the Ring Trip detector). The DET output is
an open collector with an internal pull-up of approximately 15k
to V
CC.
12
C2
TTL compatible logic input. The logic states of C1 and C2 determine the operating states (Open Circuit, Active, Ringing
or Standby) of the SLIC.
