SP3243E
3 Driver/5 Receiver Intelligent +3.0V to +5.5V
RS-232 Transceivers
The SP3243E products are 3 driver/5 receiver RS-232 transceiver solutions intended for portable
or hand-held applications such as notebook and palmtop computers. The SP3243E includes one
complementary receiver that remains alert to monitor an external device's Ring Indicate signal while
the device is shutdown. The SP3243E and EB devices feature slew-rate limited outputs for reduced
crosstalk and EMI. The "U" and "H" series are optimized for high speed with data rates up to 1Mbps,
easily meeting the demands of high speed RS-232 applications. The SP3243E series uses an internal
high-efficiency, charge-pump power supply that requires only 0.1F capacitors in 3.3V operation. This
charge pump and Exar's driver architecture allow the SP3243E series to deliver compliant RS-232
performance from a single power supply ranging from +3.0V to +5.5V. The AUTO ON-LINE feature
allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is con-
nected and a connected peripheral is turned on. Otherwise, the device automatically shuts itself down
drawing less than 1A.
FEATURES
■ Meets true EIA/TIA-232-F Standards
from a +3.0V to +5.5V power supply
■ Interoperable with EIA/TIA-232 and
adheres to EIA/TIA-562 down to a +2.7V
power source
■ AUTO ON-LINE circuitry automatically
wakes up from a 1A shutdown
■ Regulated Charge Pump Yields Stable
RS-232 Outputs Regardless of V
CC
Variations
■ Enhanced ESD Specifications:
+15kV Human Body Model
+15kV IEC61000-4-2 Air Discharge
+8kV IEC61000-4-2 Contact Discharge
■ 250 Kbps min. transmission rate (EB)
■ 1000 Kbps min. transmission rate (EU)
■ Ideal for High Speed RS-232 Applications
