DS485  
Low Power RS-485/RS-422 Multipoint Transceiver  
General Description  
Features  
n Meets TIA/EIA RS-485 multipoint standard  
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).  
n Guaranteed full load output voltage (V  
n Low quiescent current: 200 µA typ  
)
OD3  
n −7V to +12V common-mode input voltage range  
n TRI-STATE outputs on driver and receiver  
n AC performance:  
— 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  
n Half-duplex flow through pinout  
n Operates from a single 5V supply  
n Allows up to 32 transceivers on the bus  
n Current-limiting and thermal shutdown for driver  
overload protection  
The transceiver draws 200 µA of supply current when un-  
loaded or fully loaded with the driver disabled and operates  
from a single +5V supply.  
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  
guarantees a minimum of 1.5V differential output voltage  
with maximum loading across the common mode range  
(VOD3).  
The receiver has  
a failsafe feature that guarantees a  
logic-high output if the input is open circuit.  
The DS485 is available in surface mount and DIP packages  
and is characterized for Industrial and Commercial tempera-  
ture range operation.  
n Industrial temperature range operation  
n Pin and functional compatible with MAX485 and LTC485
