description
The SN75177B and SN75178B differential bus repeaters are monolithic integrated devices each designed for
one-way data communication on multipoint bus transmission lines. These devices are designed for balanced
transmission bus line applications and meet EIA Standard RS-422-A and RS-485 and CCITT
Recommendations V.11 and X.27. Each device is designed to improve the performance of the data
communication over long bus lines. The SN75177B and SN75178B are identical except for the complementary
enable inputs, which allow the devices to be used in pairs for bidirectional communication.
The SN75177B and SN75178B feature positive- and negative-current limiting 3-state outputs for the receiver
and driver. The receiver features high input impedance, input hysteresis for increased noise immunity , and input
sensitivity of ±200 mV over a common-mode input voltage range of –7 V to 12 V. The driver features thermal
shutdown for protection from line fault conditions. Thermal shutdown is designed to occur at a junction
temperature of approximately 150°C. The driver is designed to drive current loads up to 60 mA maximum.
The SN75177B and SN75178B are designed for optimum performance when used on transmission buses
employing the SN75172 and SN75174 differential line drivers, SN75173 and SN75175 differential line
receivers, or SN75176B bus transceiver. Function Tables

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)
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
