3.3V TO 5V RS-232/RS-485/RS-422 MULTIPROTOCOL TRANSCEIVER
MARCH 2018
REV. 1.0.3
GENERAL DESCRIPTION
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.
The SP337E is pin compatible to MaxLinear’s SP334.
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.
The MaxLinear-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
0.1F capacitors for complete functionality.
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.
All receivers have advanced failsafe protection to
prevent oscillation when inputs are un-connected. In
RS-232 mode, each receiver input has a 5kpull-
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.
