SP336E
3.3V / 5V PROGRAMMABLE RS-232/RS-485/RS-422 SERIAL TRANSCEIVER
JANUARY 2011
REV. 1.0.1
GENERAL DESCRIPTION
The SP336E is a monolithic serial multi-transceiver
device that contains both RS-232 and RS-485/RS-
422 line drivers and receivers. The configuration of
the SP336E can be reconfigured into eight operating
modes including RS-232 only (4TX/4RX), RS-485/
RS-422 only (2TX/2RX) full or half duplex, two RS-
232/RS-485 mixed modes. two shutdown modes and
a diagnostic loop-back mode. Modes may be
selected at any time by changing the logic state of the
three MODE pins. The device can implement a dual-
mode serial port, mixed mode ports or as an interface
signal translator. The Exar charge pumps deliver true
RS-232 driver output voltages from a single power
supply at either 3.3V or 5V. The SP336E requires
only four 0.1
μF capacitors for charge pump. A slew
rate control pin configures driver outputs for either
high data rate or slew-controlled data rates. Slew-
controlled outputs minimize problems with reflections
and ringing on long or un-terminated cables. All RS-
485 receivers or transceivers feature high impedance
which allow up to 256 transceivers on a shared bus.
When configured in RS-485/RS-422 mode, each
driver may be individually enabled or put into tri-state,
simplifying use on shared buses or bidirectional
communication. All receivers have advanced failsafe
protection to prevent oscillation when inputs are un-
connected. In RS-232 mode each receiver input has
a 5k ohm pull-down to ground. Differential 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.
