description/ordering information
The SN65176B and SN75176B differential bus transceivers are integrated circuits designed for bidirectional
data communication on multipoint bus transmission lines. They are designed for balanced transmission lines
and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.11 and X.27.
The SN65176B and SN75176B combine a 3-state differential line driver and a differential input line receiver,
both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low
enables, respectively, that can be connected together externally to function as a direction control. The driver
differential outputs and the receiver differential inputs are connected internally to form differential input/output
(I/O) bus ports that are designed to offer minimum loading to the bus when the driver is disabled or V
= 0.
CC
These ports feature wide positive and negative common-mode voltage ranges, making the device suitable for
party-line applications.

description/ordering information (continued)
The driver is designed for up to 60 mA of sink or source current. The driver features positive and negative current
limiting and thermal shutdown for protection from line-fault conditions. Thermal shutdown is designed to occur
at a junction temperature of approximately 150°C. The receiver features a minimum input impedance of 12 kΩ,
an input sensitivity of ±200 mV, and a typical input hysteresis of 50 mV.
The SN65176B and SN75176B can be used in transmission-line applications employing the SN75172 and
SN75174 quadruple differential line drivers and SN75173 and SN75175 quadruple differential line receivers.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential input/output bus voltage, are with respect to network ground terminal.
2. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) 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.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
