DS36C278  
Low Power Multipoint EIA-RS-485 Transceiver  
General Description  
Features  
n 100% RS-485 compliant  
The DS36C278 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 Built-in power up/down glitch-free circuitry  
— Permits live transceiver insertion/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  
The CMOS design offers significant power savings over its  
bipolar and ALS counterparts without sacrificing ruggedness  
against ESD damage. The device is ideal for use in battery  
powered or power conscious applications. ICC is specified at  
500 µA maximum.  
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 the high impedance state.  
n Wide common mode range: −7V to +12V  
n Receiver open input fail-safe (Note 1)

n ESD (human body model): ≥2 kV  
n Drop in replacement for:  
— LTC485, MAX485, DS75176, DS3695  
The receiver incorporates a fail safe circuit which guarantees  
a high output state when the inputs are left open. (Note 1)  
The DS36C278T is fully specified over the industrial tem-  
perature range (−40˚C to +85˚C).
