SNLS122C –JULY 1998–REVISED APRIL 2013  
DS485 Low Power RS-485/RS-422 Multipoint Transceiver  
Check for Samples: DS485

FEATURES  
DESCRIPTION  
The DS485 is a low-power transceiver for RS-485  
and RS-422 communication. The device contains one  
driver and one receiver. The drivers slew rate allows  
for operation up to 2.5 Mbps (see Applications  
Information section).  
•
•
•
•
Meets TIA/EIA RS-485 Multipoint Standard  
ensured Full Load Output Voltage (V OD3  
)
Low Quiescent Current: 200 μA typ  
−7V to +12V Common-Mode Input Voltage  
Range  
The transceiver draws 200 μA of supply current when  
unloaded or fully loaded with the driver disabled and  
operates from a single +5V supply.  
•
•
TRI-STATE Outputs on Driver and Receiver  
AC Performance:  
The driver is short-circuit current limited and is  
protected against excessive power dissipation by  
thermal shutdown circuitry that places the driver  
outputs into TRI-STATE (High Impedance state)  
under fault conditions. The driver ensures a minimum  
of 1.5V differential output voltage with maximum  
loading across the common mode range (VOD3).

Driver Transition Time: 25 ns typ  
Driver Propagation Delay: 40 ns typ  
Driver Skew: 1 ns typ  
Receiver Propagation Delay: 200 ns typ  
Receiver Skew: 20 ns typ

•
•
Half-Duplex Flow Through Pinout  
Operates From a Single 5V Supply  
Allows Up To 32 Transceivers on the Bus  
The receiver has a failsafe feature that ensures a  
logic-high output if the input is open circuit.  
The DS485 is available in 8-pin SOIC and PDIP  
packages and is characterized for Industrial and  
Commercial temperature range operation.
