ADM3485EARZ-REEL7 Description

The ADM3485E is a 3.3 V, low power data transceiver with±15 kV ESD protection, suitable for half-duplex communication on multipoint bus transmission lines. The ADM3485Eis designed for balanced data transmission and complies withTIA/EIA standards RS485 and RS-422. The ADM3485E is ahalf-duplex transceiver that shares differential lines and hasseparate enable inputs for the driver and the receiver.

The devices have a 12 kΩ receiver input impedance, whichallows up to 32 transceivers on a bus. Because only one drivershould be enabled at any time, the output of a disabled orpowered-down driver is tristated to avoid overloading the bus.The receiver has a fail-safe feature that ensures a logic highoutput when the inputs are floating. Excessive power dissipationcaused by bus contention or by output shorting is preventedwith a thermal shutdown circuit. The part is fully specified over the industrial temperature rangeand is available in an 8-lead narrow SOIC package.
