GENERAL DESCRIPTION  
The ADM3485E is a 3.3 V, low power data transceiver with  
±±5 ꢀV EꢁD protection, suitable for half-duplex communi-  
cation on multipoint bus transmission lines. The ADM3485E  
is designed for balanced data transmission and complies with  
TIA/EIA standards Rꢁ­485 and Rꢁ-422. The ADM3485E is a  
half-duplex transceiver that shares differential lines and has  
separate enable inputs for the driver and the receiver.  
should be enabled at any time, the output of a disabled or  
powered-down driver is tristated to avoid overloading the bus.  
The receiver has a fail-safe feature that ensures a logic high  
output when the inputs are floating. Excessive power dissipation  
caused by bus contention or by output shorting is prevented  
with a thermal shutdown circuit.  
The part is fully specified over the industrial temperature range  
and is available in an 8-lead narrow ꢁOIC pacꢀage.  
The devices have a ±2 ꢀΩ receiver input impedance, which  
allows up to 32 transceivers on a bus. Because only one driver
