SP3223E/3243E
Intelligent +3.0V to +5.5V RS-232 Transceivers
The SP3223E and 3243E products are RS-232 transceiver solutions intended for portable or
hand-held applications such as notebook and palmtop computers. The SP3223E and 3243E
use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors
in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3223E/
3243E series to deliver compliant RS-232 performance from a single power supply ranging
from +3.3V to +5.0V. The SP3223E is a 2-driver/2-receiver device, and the SP3243E is a
3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.
The SP3243E includes one complementary receiver that remains alert to monitor an external
device's Ring Indicate signal while the device is shutdown.
The AUTO ON-LINE® feature allows the device to automatically "wake-up" during a shutdown
state when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise,
the device automatically shuts itself down drawing less than 1µA.
■ 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 1µA shutdown
■ Minimum 120Kbps 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 IEC1000-4-2 Air Discharge
+8KV IEC1000-4-2 Contact Discharge
