FEATURES  
DESCRIPTION  
The DS36C278 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.  
2
100% RS-485 Compliant  
Guaranteed RS-485 Device Interoperation  
Low Power CMOS Design: ICC 500 μA Max  
Built-In Power Up/Down Glitch-Free Circuitry  
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.  
Permits Live Transceiver  
Insertion/Displacement  
PDIP and SOIC Packages Available  
Industrial Temperature Range: 40°C to  
+85°C  
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  
the high impedance state.  
On-Board Thermal Shutdown Circuitry  
Prevents Damage to the Device in the Event  
of Excessive Power Dissipation  
Wide Common Mode Range: 7V to +12V  
(1)  
Receiver Open Input Fail-Safe  
¼ Unit Load (DS36C278): 12 Nodes  
½ Unit Load (DS36C278T): 64 Nodes  
ESD (Human Body Model): 2 kV  
Drop in Replacement for:  
The receiver incorporates a fail safe circuit which  
guarantees a high output state when the inputs are  
(1)  
left open.  
The DS36C278T is fully specified over the industrial  
LTC485, MAX485, DS75176, DS3695  
temperature range (40°C to +85°C).  
(1) Non-terminated, open input only
