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 compat-  
ible 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 DIP and SOIC packages available  
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  
n Wide common mode range: −7V to +12V  
applications where the device may be disabled for extended  
periods of time.  
The driver and receiver outputs feature TRI-STATE® capabil-  
ity. 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.  
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.

n Drop-in replacement for:  
— LTC485 MAX485 DS75176 DS3695  
The DS36C279T is fully specified over the industrial tem-  
perature range (−40˚C to +85˚C).
