SP3239E
Intelligent +3.0V to +5.5V RS-232 Transceiver
The SP3239E device is an RS-232 transceiver solution intended for portable or hand-held applications
such as notebook and palmtop computers. The SP3239E 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 SP3239E device to deliver compliant RS-232 performance from a single power
supply ranging from +3.0V to +5.5V. The SP3239E is a 5-driver / 3-receiver device that is ideal for laptop
/ notebook computer and PDA applications. The SP3239E includes one complementary receiver that
remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.
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
■ Minimum 250Kbps data rate under load
■ 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
