Pin Description
Pin #
Name
Description
1
TIP
Tip Lead.
Connects to the “Tip” lead (A-wire) of the telephone line.
2
VDD
Positive Power Supply
Voltage. Normally +5V. This provides current for both internal
circuitry as well as the loop. Not internally connected to pin 12.
3
RING
Ring Lead.
Connects to the “Ring” lead (B-wire) of the telephone line.
4
RF
Ring Feed.
Connect to the Ring Relay contact. See Figure 5.
5
TF
Leave open circuit
6
VBAT
Battery Voltage Supply.
Normally -24V or -48V. Not internally connected to pin 14.
7
AGND
Analog Ground.
Supply and battery ground. Internally connected to pin 13. For
optimum performance connect pin 7 to pin 13.
8
V
EE
LED
Negative Power Supply Voltage
. Normally -5V.
9
LED Drive (Output).
Drives an LED directly. A logic low indicates an off-hook condition.
10
SHK
Switch Hook Detect (Output).
A logic low indicates an off-hook condition.
11
IC
Internal Connection
. This pin is connected internally
12
V
DD
Positive Power Supply
Voltage. Normally +5V. This provides current for both internal
circuitry as well as the loop.
13
AGND
Analog Ground.
Supply and battery ground. Internally connected to pin 13. For
optimum performance connect pin 13 to pin 7.
14
V
BAT
MUTE
Battery Voltage Supply.
Normally -24V or -48V. Not internally connected to pin 6.
15
MUTE (Input)
. A logic low will mute signals coming from Tip-Ring to the JUNC.
16
JUNC
Receive/transmit audio speech path
. (Referenced to 0V GND).
17
RRD
Ring Relay Drive (Output).
Connects to the ring relay coil. A logic low activates the
relay.
18
RGND
Relay Ground.
Return path for relay supply votlage. Normally connected to AGND.
19
RRC
Ring Relay Control (Input)
. A logic high activates the Ring Relay Drive (RRD) outputs.
20
VRLY
Relay Positive Supply Voltage. Normally +5V. Connects to the relay coil and the relay
supply voltage. An internal clamp diode from VRLY to RGND is provided.
