GENERAL DESCRIPTION  
Excessive power dissipation caused by bus contention or by  
output shorting is prevented by a thermal shutdown circuit.  
This feature forces the driver output into a high impedance  
state if, during fault conditions, a significant temperature  
increase is detected in the internal driver circuitry.  
The ADM3485E is a low power differential line transceiver  
designed to operate using a single +3.3 V power supply. Low  
power consumption makes it ideal for power sensitive applica-  
tions. It is suitable for communication on multipoint bus trans-  
mission lines. Internal protection against electrostatic discharge  
(ESD) and electrical fast transient (EFT) allows operation in  
electrically harsh environments.  
The receiver contains a fail-safe feature that results in a  
logic high output state if the inputs are unconnected  
(floating).  
It is intended for balanced data transmission and complies with  
both EIA Standards RS-485 and RS-422. It contains a differen-  
tial line driver and a differential line receiver, and is suitable for  
half duplex data transfer.  
The ADM3485E is fabricated on BiCMOS, an advanced  
mixed technology process combining low power CMOS  
with fast switching bipolar technology.  
The ADM3485E is fully specified over the industrial tem-  
perature range and is available in 8-lead DIP and SOIC  
packages.  
The input impedance is 19 kΩ allowing up to 50 transceivers to  
be connected on the bus.
