SLLS668A–FEBRUARY 2006–REVISED MAY 2006  
5 V FULL-DUPLEX RS-485/RS-422 DRIVERS AND BALANCED RECEIVERS  
FEATURES  
DESCRIPTION

•
Designed for INTERBUS Applications  
The SN65HVD179 is a differential line driver and  
differential-input line receiver that operate with a 5-V  
power supply. Each driver and receiver has separate  
input and output pins for full-duplex bus  
communication designs. They are designed for  
balanced transmission lines and interoperation with  
ANSI TIA/EIA-485A, TIA/EIA-422-B, ITU-T v.11, and  
ISO 8482:1993 standard-compliant devices.  
Balanced Receiver Thresholds  
1/2 Unit-Load (up to 64 nodes on the bus)  
Bus-Pin ESD Protection 15 kV HBM  
Bus-Fault Protection of –7V to 12V  
Thermal Shutdown Protection  
Power-Up/Down Glitch-free Bus Inputs and  
Outputs  
The differential bus driver and receiver are  
monolithic, integrated circuits designed for full-duplex  
bi-directional data communication on multipoint  
bus-transmission lines at signaling rates(1) up to 25  
Mbps. The SN65HVD179 is fully enabled with no  
external enabling pins.  
APPLICATIONS

•
Digital Motor Control  
Utility Meters  
Chassis-to-Chassis Interconnections  
Electronic Security Stations  
Industrial, Process, and Building Automation  
Point-of-Sale (POS) Terminals and Networks  
DTE/DCE Interfaces  
The 1/2 unit load receiver has a higher receiver input  
resistance. This results in lower bus leakage currents  
over the common-mode voltage range, and reduces  
the total amount of current that a 485 driver is forced  
to source or sink when transmitting.  
The balanced differential receiver input threshold  
makes the SN65HVD179 more compatible with  
fieldbus requirements that define an external failsafe  
structure.  
(1) The signaling rate of a line is the number of voltage  
transitions that are made per second expressed in the units  
bps (bits per second).
