SP337E

3.3V TO 5V RS-232/RS-485/RS-422 MULTIPROTOCOL TRANSCEIVER

MARCH 2011

REV. 1.0.2

GENERAL DESCRIPTION

FEATURES

The SP337E is a dual mode serial transceiver

containing both RS-232 and RS-485/422 line drivers

and receivers. The RS-232 mode provides three

drivers and five receivers to support all eight signals

commonly used in the DB9 serial port connector

(3TX/5RX). In RS-485 mode the device features two

independent high speed RS-485/422 transmit and

receive channels (2TX/2RX). The default RS-485

configuration is full-duplex, but half-duplex operation

can be obtained by tying together the TX and RI pins,

and the TXEN and RXEN signals.

• 3.3V to 5V Single Supply Operation

• Robust +/-15kV ESD Protection

■ Human Body Model

• Max Data Rate of 15Mbps in RS-485 mode

and up to 1Mbps in RS-232 mode (SP337EU)

• 3 Drivers, 5 Receivers RS-232/V.28

• 2 Drivers, 2 Receivers RS-485/RS-422

■ Full-Duplex Configuration

The SP337E is pin compatible to Exar’s SP334.

■ 1/8th Unit Load, up to 256 receivers on bus

The SP337EB features a maximum data rate of

250kbps in RS-232 mode and a maximum data rate

of 15Mbps in RS-485. However, the SP337EU

features a maximum data rate of 1Mbps in RS-232

mode and a maximum data rate of 15Mbps in RS-485

mode.

• RS-485 Advanced Failsafe on Open, Short or

Terminated Lines

• Full Differential Driver Tri-State (Hi-Z) Control

• Receiver Output Tri-State Control

• WSOIC-28 or TSSOP-28 Package

The Exar-patented high efficiency charge pumps

(5,306,954) deliver true RS-232 driver output

voltages from a single power supply from 3.3V to 5V.

Charge pump outputs are self-monitored to minimize

power consumption. The SP337E requires only four

0.1μF capacitors for complete functionality.

TYPICAL APPLICATIONS

• Dual Protocol Serial Ports (RS-232 or RS-485)

• Industrial Computers

All RS-485 receivers or transceivers feature high

impedance inputs which allow up to 256 transceivers

on a single shared bus. When configured in RS-485

mode, each driver may be individually enabled or put

into tri-state, simplifying use on shared buses or for

bidirectional communication. The RS-485/422 drivers

can be disabled (high-Z output) by the TXEN enable

pin. The RS-232 receiver outputs can be disabled by

the RXEN enable pin.

• Industrial and Process Control Equipment

• Point-Of-Sales Equipment

• Networking Equipment

• HVAC Controls Equipment

• Building Security Equipment

All receivers have advanced failsafe protection to

prevent oscillation when inputs are un-connected. In

RS-232 mode, each receiver input has a 5kΩ pull-

down to ground. in RS-485 mode, receivers will

default to output logic 1 if inputs are floating, shorted,

or open but terminated.

All driver outputs and receiver inputs are protected

against ESD strikes up to +/-15,000 volts.
