SP485E

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

Transceivers

General Description

The SP485 is low-power transceivers for RS-485 and RS-

422 communication. IC contains one driver and one receiver.

The driver slew rates of the SP485 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 SP485 is

designed for half-duplex applications.

Features

Low Quiescent Current: 300µA

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
