RS-485/RS-422 Transceivers

General Description

Beneﬁts and Features

●ꢀ IntegratedꢀProtectionꢀIncreasesꢀRobustnessꢀ

Devices in the MAX3483AE family (MAX3483AE/

MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE)

are ±20kV ESD-protected RS-485/422 transceivers,

optimized for extended cable runs in noisy environments.

All devices operate from a single 3.3V supply.

•ꢀ HighꢀESDꢀProtection

±20kV HBM ESD per JEDEC JS-001-2012

±15kV Air Gap per IEC 61000-4-2

±8kV Contact ESD per IEC 61000-4-2

ꢀ

•ꢀ Short-CircuitꢀProtectedꢀOutputs

The MAX3483AE and MAX3485AE are half-duplex transceivers.

The MAX3488AE, MAX3490AE, and MAX3491AE are

full-duplex transceivers. The MAX3483AE/85AE have a

1-unit load receiver input impedance, allowing up to 32

transceivers on the bus. The MAX3488AE/90AE/91AE

have a 1/4-unit load receiver input impedance, allowing up

to 128 transceivers on the bus. Each transceiver includes

a fail-safe receiver, ensuring that the receiver output (RO)

is high when inputs are shorted, open, or connected to a

three-state bus.

All devices feature enhanced electrostatic discharge (ESD)

protection. All transmitter outputs and receiver inputs are

protected to ±20kV HBM ESD, ±15kV Air-Gap ESD and

±8kV Contact ESD in accordance to IEC 61000-4-2.

●ꢀ Telecommuncations

The MAX3483AE, MAX3485AE, MAX3488AE, and

MAX3490AE are available in industry standard 8-pin SO

package, while the MAX3491AE is available in a 14-pin

SO package.
