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.
