RS-485 Transceiver with Integrated Low-Dropout

Regulator and AutoDirection Control

0–MAX3415E

General Description

Features

The MAX13410E–MAX13415E are half-duplex RS-485-/RS-

422-compatible transceivers optimized for isolated appli-

cations. These devices feature an internal low-dropout

regulator (LDO), one driver, and one receiver. The inter-

nal LDO allows the part to operate from an unregulated

power supply of up to 28V. The AutoDirection feature

reduces the number of optical isolators needed in isolat-

ed applications. Other features include enhanced ESD

protection, fail-safe circuitry, slew-rate limiting, and full-

speed operation.

♦ Wide +6V to +28V Input Supply Range

♦ +5V Output Supplies Up to 20mA to External

Circuitry

♦ Internal LDO

♦ Low 65µA (typ) Shutdown Supply Current

♦ Extended ESD Protection

external circuitry with up to 20mA to further reduce exter-

nal components. The MAX13410E/MAX13411E do not

have a 5V output and come in industry-compatible

pinouts. This allows easy replacement in existing designs.

♦ -40°C to +85°C Operating Temperature Range

♦ Fail-Safe

♦ Slew-Rate Limited and Full-Speed Versions

♦ Up to 16Mbps Data Rate on Full-Speed Versions

The MAX13410E–MAX13415E feature a 1/8-unit load

receiver input impedance, allowing up to 256 trans-

ceivers on the bus. All driver outputs are ESD protected

using the Human Body Model. These devices also

include fail-safe circuitry (MAX13410E/MAX13411E/

MAX13414E/MAX13415E only), guaranteeing a logic-

high receiver output when the receiver inputs are open

or shorted. The receiver outputs a logic-high when the

transmitter on the terminated bus is disabled (high

impedance).

Pin Configurations

The MAX13412E/MAX13413E feature Maxim’s propri-

etary AutoDirection control. This architecture eliminates

the need for the DE and RE control signals. In isolated

applications, this reduces the cost and size of the sys-

tem by reducing the number of optical isolators required.

The MAX13410E/MAX13412E/MAX13414E feature

reduced slew-rate drivers that minimize EMI and reduce

reflections caused by improperly terminated cables,

allowing error-free transmission up to 500kbps. The

MAX13411E/MAX13413E/MAX13415E are not slew-rate

limited, allowing transmit speeds up to 16Mbps.
