RD
Ring Relay Driver - An active low open collector output. Used to drive a relay that switches ring-
ing signals onto the 2-Wire line.
24
38
VFB
Feedback input to the tip feed amplifier; may be used in conjunction with transmit output signal
and the spare op-amp to accommodate 2W line impedance matching.
25
39
TF2
Tip Feed - A low impedance analog output connected to the TIP terminal through a feed resistor.
Functions with the RF terminal to provide loop current, and to feed voice signals to the telephone
set and to sink longitudinal currents. Must be tied to TF1.
NA
40
TF1
Tie directly to TF2 in the PLCC application.
26
41
RF1
Ring Feed - A low impedance analog output connected to the RING terminal through a feed re-
sistor. Functions with the TF terminal to provide loop current, feed voice signals to the telephone
set, and to sink longitudinal currents. Tie directly to RF2.
NA
42
RF2
Tie directly to RF1 in the PLCC application.
27
43
VB-
The battery voltage source. The most negative supply.
28
44
C2
Capacitor #2 - An external capacitor to be connected between this terminal and ground. It pre-
vents false ring trip detection from occurring when longitudinal currents are induced onto the sub-
scriber loop from power lines and other noise sources. This capacitor should be nonpolarized.
1, 5, 6, 7,
15, 16,
17, 21,
23, 26,
28, 29, 30
NC
No internal connection.
NOTE:
1. All grounds (AG, BG, DG) must be applied before V
B+
or V
B-
. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
