FEATURES  
DESCRIPTION  
The DS36C279 is a low power differential bus/line  
transceiver designed to meet the requirements of RS-  
485 Standard for multipoint data transmission. In  
addition it is compatible with TIA/EIA-422-B.  
•
100% RS-485 Compliant  
Specified RS-485 Device Interoperation  
–
•
•
Low Power CMOS Design: ICC 500 μA Max  
Automatic Sensing Sleep Mode  
The sleep mode feature automatically puts the device  
in a power saving mode when both the driver and  
receiver are disabled.(2) The device is ideal for use in  
power conscious applications where the device may  
be disabled for extended periods of time.  
–
Reduces ICC to 10 μA Maximum  
•
Built-in Power Up/Down Glitch-Free Circuitry  
–
Permits Live Transceiver  
Intersection/Displacement  
The driver and receiver outputs feature TRI-STATE  
capability. The driver outputs operate over the entire  
common mode range of −7V to +12V. Bus contention  
or fault situations that cause excessive power  
dissipation within the device are handled by a thermal  
shutdown circuit, which forces the driver outputs into  
a high impedance state.

•
SOIC Packages  
Industrial Temperature Range: −40°C to  
+85°C  
•
On-Board Thermal Shutdown Circuitry  
–
Prevents Damage to the Device in the Event  
of Excessive Power Dissipation  
The receiver incorporates a fail safe circuit which  
ensures a high output state when the inputs are left  
open.(3)  
•
•
•
•
•
•
Wide Common Mode Range: −7V to +12V  
Receive Open Input Fail-Safe(1)  
¼ Unit Load (DS36C279): ≥ 128 Nodes  
½ Unit Load (DS36C279T): ≥ 64 Nodes  
ESD (Human Body Model): ≥ 2 kV  
Drop-In Replacement for:  
The DS36C279T is fully specified over the industrial  
temperature range (−40°C to +85°C).  
(2) Device enters sleep mode if enable conditions are held > 600
