description
The SN65LBC175A and SN75LBC175A are
quadruple differential line receivers with 3-state
outputs, designed for TIA/EIA-485 (RS-485),
TIA/EIA-422 (RS-422), and ISO 8482 (Euro
RS-485) applications.
These devices are optimized for balanced
multipoint bus communication at data rates up to
and exceeding 50 million bits per second. The
transmission media may be twisted-pair cables,
printed-circuit board traces, or backplanes. The
ultimate rate and distance of data transfer is
dependent upon the attenuation characteristics of
the media and the noise coupling to the
environment.

Each receiver operates over a wide range of positive and negative common-mode input voltages, and features
ESD protection to 6 kV, making it suitable for high-speed multipoint data transmission applications in harsh
environments. These devices are designed using LinBiCMOSt, facilitating low power consumption and
inherent robustness.
Two EN inputs provide pair-wise enable control, or these can be tied together externally to enable all four drivers
with the same signal.
The SN75LBC175A is characterized for operation over the temperature range of 0°C to 70°C. The
SN65LBC175A is characterized over the temperature range from −40°C to 85°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
LinBiCMOS is a trademark of Texas Instruments.
1The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second).

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

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)
