Pin Descriptions
PLCC
SYMBOL
DESCRIPTION
1
TIP
TIP power amplifier output.
2
BGND
Battery Ground - To be connected to zero potential. All loop current and longitudinal current flow from this ground. Inter-
nally separate from AGND but it is recommended that it is connected to the same potential as AGND.
3
VBL
Low battery supply connection.
4
VBH
High battery supply connection for the most negative battery.
5
SW+
Uncommitted switch positive terminal. This pin is a no connect (NC) on the HC55180, HC55183 and HC55184.
6
SW-
Uncommitted switch negative terminal. This pin is a no connect (NC) on the HC55180, HC55183 and HC55184.
7
SWC
Switch control input. This TTL compatible input controls the uncommitted switch, with a logic “0” enabling the switch and
logic “1” disabling the switch. This pin is a no connect (NC) on the HC55180, HC55183 and HC55184.
8
F2
Mode control input - MSB. F2-F0 for the TTL compatible parallel control interface for controlling the various modes of
operation of the device.
9
F1
Mode control input.
10
F0
Mode control input.
11
E0
Detector Output Selection Input. This TTL input controls the multiplexing of the SHD (E0 = 1) and GKD (E0 = 0)
comparator outputs to the DET output based upon the state at the F2-F0 pins (see the Device Operating Modes table
shown on page 2).
12
DET
Detector Output - This TTL output provides on-hook/off-hook status of the loop based upon the selected operating mode.
The detected output will either be switch hook, ground key or ring trip (see the Device Operating Modes table shown on
page 2).
13
ALM
Thermal Shutdown Alarm. This pin signals the internal die temperature has exceeded safe operating temperature
(approximately 175
o
C) and the device has been powered down automatically.
14
AGND
Analog ground reference. This pin should be externally connected to BGND.
15
BSEL
Selects between high and low battery, with a logic “1” selecting the high battery and logic “0” the low battery. This pin is
a no connect (NC) on the HC55180.
16
NC
This pin is a no connect (NC) for all the devices.
17
POL
External capacitor on this pin sets the polarity reversal time. This pin is a no connect on the HC55182 and HC55183.
18
VRS
Ringing Signal Input - Analog input for driving 2-wire interface while in Ring Mode.
19
VRX
Analog Receive Voltage - 4-wire analog audio input voltage. AC couples to CODEC.
20
VTX
Transmit output voltage - Output of impedance matching amplifier, AC couples to CODEC.
21
VFB
Feedback voltage for impedance matching. This voltage is scaled to accomplish impedance matching.
22
-IN
Impedance matching amplifier summing node.
23
VCC
Positive voltage power supply, usually +5V.
24
CDC
DC Biasing Filter Capacitor - Connects between this pin and V
CC
.
25
RTD
Ring trip filter network.
26
ILIM
Loop Current Limit programming resistor.
27
RD
Switch hook detection threshold programming resistor.
28
RING
RING power amplifier output.
HC55180, HC55181, HC55182, HC55183, HC55184
