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
