DESCRIPTION/ORDERING INFORMATION  
The SN55182 dual differential line receiver is  
designed to sense small differential signals in the  
presence of large common-mode noise. This device  
gives TTL-compatible output signals as a function of  
the polarity of the differential input voltage. The  
frequency response of each channel can be easily  
controlled by a single external capacitor to provide  
immunity to differential noise spikes. The output goes  
to a high level when the inputs are open circuited. A  
strobe input (STRB) is provided that, when in the low  
level, disables the receiver and forces the output to a  
high level.  
The receiver is of monolithic single-chip construction, and both halves of the dual circuits use common  
power-supply and ground terminals.  
The SN55182 is characterized for operation over the full military temperature range of –55°C to 125°C.

(1) The absolute maximum ratings under any condition are limited by the constraints of the silicon process. Stresses above these ratings  
may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These  
are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied.  
(2) All voltage values, except differential voltages, are with respect to network ground terminal.  
(3) Differential voltage values are at the noninverting terminal with respect to the inverting terminal.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check  
http://www.ti.com/productcontent for the latest availability information and additional product content details.  
TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
