E1
TTL compatible logic input. The logic state of E1 in conjunction with the logic state of C1 determines which detector
is gated to the DET output.
13
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.
14
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 VCC.
15
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.
16
C1
TTL compatible logic input. The logic states of C1 and C2 determine the operating states (Open Circuit, Active,
Ringing or Standby) of the SLIC.
17
RDC
DC feed current programming resistor pin. Constant current feed is programmed by resistors RDC1 and RDC2
connected in series from this pin to the receive summing node (RSN). The resistor junction point is decoupled to
AGND to isolate the AC signal components.
18
AGND
Analog ground.
19
RSN
Receive Summing Node. The AC and DC current flowing into this pin establishes the metallic loop current that flows
between tip and ring. The magnitude of the metallic loop current is 1000 times greater than the current into the RSN
pin. The constant current programming resistors and the networks for program receive gain and 2-wire impedance
all connect to this pin.
20
VEE
-5V power supply.
21
VTX
Transmit audio output. This output is equivalent to the TIP to RING metallic voltage. The network for programming
the 2-wire input impedance connects between this pin and RSN.
22
HPR
RING side of AC/DC separation capacitor CHP. CHP is required to properly separate the ring AC current from the
DC loop current. The other end of CHP is connected to HPT.
1
HPT
TIP side of AC/DC separation capacitor CHP. CHP is required to properly separate the tip AC current from the DC
loop current. The other end of CHP is connected to HPR.
2
RD
Loop current programming resistor. Resistor RD sets the trigger level for the loop current detect circuit. A filter
capacitor CD is also connected between this pin and VEE.
3
DT
Input to ring trip comparator. Ring trip detection is accomplished by connecting an external network to a comparator
in the SLIC with inputs DT and DR.
4
DR
Input to ring trip comparator. Ring trip detection is accomplished by connecting an external network to a comparator
in the SLIC with inputs DT and DR.
TIPSENSE
Internally connected to output of tip power amplifier.
5
TIPX
Output of tip power amplifier.
6
RINGX
Output of ring power amplifier.
N/C
No internal connection.
