DescripTion  
The LTC®485 is a low power differential bus/line trans-  
ceiverdesignedformultipointdatatransmissionstandard  
RS485 applications with extended common mode range  
(12V to –7V). It also meets the requirements of RS422.

The CMOS design offers significant power savings over  
its bipolar counterpart without sacrificing ruggedness  
against overload of ESD damage.

Power-Up/Down ꢀlitch-Free Driver Outputs  
Permit Live Insertion or Removal of Transceiver  
n
The driver and receiver feature three-state outputs, with  
the driver outputs maintaining high impedance over the  
entire common mode range. Excessive power dissipa-  
tion caused by bus contention or faults is prevented by a  
thermal shutdown circuit which forces the driver outputs  
into a high impedance state.  
Driver Maintains High Impedance in Three-State  
or with the Power Off

Combined Impedance of a Driver Output and  
Receiver Allows Up to 32 Transceivers on the Bus

30ns Typical Driver Propagation Delays  
with 5ns Skew for Up to 2.5MB Operation  
The receiver has a fail-safe feature which guarantees a  
high output state when the inputs are left open.

Pin Compatible with ±±0V Protected LT1785 and  
52Mbps LTC1±85  
The LTC485 is fully specified over the commercial and  
extended industrial temperature range.
