MAX485

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

Transceivers

General Description

The MAX485 is low-power transceivers for RS-485 and RS-

422 communication. IC contains one driver and one receiver.

The driver slew rates of the MAX485 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.

ORDERING INFORMATION

MAX485CPA Plastic DIP

MAX485CSA SOIC

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

logic-high output if the input is open circuit. The MAX485 is

designed for half-duplex applications.

Features

Low Quiescent Current: 300µA

-7V to +12V Common-Mode Input Voltage Range

Three-State Outputs

30ns Propagation Delays, 5ns Skew

Full-Duplex and Half-Duplex Versions Available

Operate from a Single 5V Supply

Allows up to 32 Transceivers on the Bus

Data rate: 2,5 Mbps

Current-Limiting and Thermal Shutdown for Driver Overload Protection

The transmitter outputs and receiver inputs are protected to ±15kV Air ESD.
