ADM485

Low-Power, Slew-Rate-Limited RS-485/RS-422

Transceivers

General Description

The ADM485 is low-power transceivers for RS-485 and RS-

422 communication. IC contains one driver and one receiver.

The driver slew rates of the ADM485 is not limited, allowing

them to transmit up to 2.5Mbps.

These transceivers draw between 120µA and 500µA of

supply current when unloaded or fully loaded with disabled

drivers. All parts operate from a single 5V supply. Drivers are

short-circuit current limited and are protected against

excessive power dissipation by thermal shutdown circuitry

that places the driver outputs into a high-impedance state.

The receiver input has a fail-safe feature that guarantees a

logic-high output if the input is open circuit. The ADM485

is designed for half-duplex applications.
