DS36C279  
Low Power EIA-RS-485 Transceiver with Sleep Mode  
General Description  
Features  
n 100% RS-485 compliant  
The DS36C279 is a low power differential bus/line trans-  
ceiver designed to meet the requirements of RS-485 Stan-  
dard for multipoint data transmission. In addition it is com-  
patible with TIA/EIA-422-B.  
— Guaranteed RS-485 device interoperation  
n Low power CMOS design: ICC 500 µA max  
n Automatic sensing sleep mode  
— Reduces ICC to 10 µA maximum  
n Built-in power up/down glitch-free circuitry  
The sleep mode feature automatically puts the device in a  
power saving mode when both the driver and receiver are  
††  
disabled. The device is ideal for use in power conscious  
— Permits live transceiver intersection/displacement  
n SOIC packages  
n Industrial temperature range: −40˚C to +85˚C  
n On-board thermal shutdown circuitry  
— Prevents damage to the device in the event of  
excessive power dissipation  
applications where the device may be disabled for extended  
periods of time.  
The driver and receiver outputs feature TRI-STATE® capa-  
bility. The driver outputs operate over the entire common  
mode range of −7V to +12V. Bus contention or fault situa-  
tions that cause excessive power dissipation within the de-  
vice are handled by a thermal shutdown circuit, which forces  
the driver outputs into a high impedance state.  
n Wide common mode range: −7V to +12V  
n Receive open input fail-safe (Note 1)

unit load (DS36C279): 128 nodes  
unit load (DS36C279T): 64 nodes  
The receiver incorporates a fail safe circuit which guarantees  
a high output state when the inputs are left open.

The DS36C279T is fully specified over the industrial tem-  
perature range (−40˚C to +85˚C).
