Complete, Isolated RS-485/RS-422

Data Interface

_________________General Description

Next-Generation Device Features

♦ For Integrated ESD Protection

The MAX1480A/MAX1480B/MAX1480C/MAX1490A/

MAX1490B are complete, electrically isolated, RS-485/

RS-422 data-communications interface solutions in a

hybrid microcircuit. Transceivers, optocouplers, and a

transformer provide a complete interface in a standard

DIP package. A single +5V supply on the logic side pow-

ers both sides of the interface.

MAX1480E/MAX1490E: ±15kV ESD-Protected,

Isolated RS-485/RS-422 Data Interfaces

♦ For Space-Constrained Applications

MAX3157: High CMRR, RS-485 Transceiver with

±50V Isolation

_______________Ordering Information

The MAX1480B/MAX1480C/MAX1490B feature reduced-

slew-rate drivers that minimize EMI and reduce reflec-

tions caused by improperly terminated cables, allowing

error-free data transmission at data rates up to 250kbps.

The MAX1480A/MAX1490A driver slew rate is not limited,

allowing transmission rates up to 2.5Mbps. The

MAX1480A/B/C are designed for half-duplex communi-

cation, while the MAX1490A/B feature full-duplex com-

munication.

Ordering Information continued at end of data sheet.

Data rate for “A” parts is up to 2.5Mbps. Data rate for “B” and

“C” parts is up to 250kbps.

_____________________Selection Table

Drivers are short-circuit current limited and protected

against excessive power dissipation by thermal shut-

down circuitry that places the driver outputs into a high-

impedance state. The receiver input has a fail-safe

feature that guarantees a known output (RO low for the

MAX1480A/B/C, RO high for the MAX1490A/B/C) if the

input is open circuit.
