DATASHEET
HC55183, HC55184
Extended Reach Ringing SLIC Family
The RSLIC18™ family of ringing subscriber line interface
circuits (RSLIC) supports analog Plain Old Telephone
Service (POTS) in short and medium loop length, wireless
and wireline applications. Ideally suited for remote
subscriber units, this family of products offers flexibility to
designers with high ringing voltage and low power
consumption system requirements.
The HC55183 and HC55184 family operates up to 75V, and
the HC55185 family operates to 100V, which translates
directly to the amount of ringing voltage supplied to the end
subscriber. With 100V operating voltage, subscriber loop
lengths can be extended up to 500 (i.e., 5,000 feet) and
beyond.
Other key features across the product family include: low
power consumption, ringing using sinusoidal or trapezoidal
waveforms, robust auto-detection mechanisms for when
subscribers go on or off hook, and minimal external discrete
application components. Integrated test access features are
also offered on selected products to support loopback
testing as well as line measurement tests.
There are 2 product offerings in the RSLIC18 family:
HC55183 and HC55184. The architecture for this family is
based on a voltage feed amplifier design using low fixed loop
gains to achieve high analog performance with low
susceptibility to system induced noise.

NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb
and Pb-free soldering operations). Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.

3. These parameters are controlled via design or process parameters and are not directly tested. These parameters are characterized upon initial
design release and upon design changes which would affect these characteristics.
4. Differential Ringing Gain is measured with VRS = 0.663 V
RMS
for -85V devices and VRS = 0.575 V
RMS
for -75V devices.
5. These parameters are specified at low battery operation.The external supply is set to BSEL = 0.
6. Forward Active and Reverse Active performance is guaranteed for the HC55184 device only. The HC55183 is specified for Forward Active
operation only.
