SP3223EH/3243EH
High Speed Intelligent +3.0V to +5.5V
RS-232 Transceivers
features
description
The SP3223EH and 3243EH products are RS-232 transceiver solutions
intended for portable or hand-held applications such as notebook and
palmtop computers. The "H" series is based on Sipex's SP3223E/3243E
series and has been enhanced for high speed. The data rate is improved
to 460kbps, easily meeting the demands of high speed RS-232 applica-
tions. The SP3223EH and 3243EH 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 SP3223EH/
3243EH series to deliver compliant RS-232 performance from a single
power supply ranging from +3.3V to +5.0V. The SP3223EH is a 2-driv-
er/2-receiver device, and the SP3243EH is a 3-driver/5-receiver device,
ideal for laptop/notebook computer and PDA applications. The SP3243EH
includes one complementary receiver that remains alert to monitor an
external device's Ring Indicate signal while the device is shutdown.
■ 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
1mA shutdown
■ Regulated charge pump yields
stable RS-232 outputs regard-
less of V variations
CC
■ Enhanced ESD specifications:
• ±15kV Human Body Model
• ±15kV IEC1000-4-2 Air
Discharge
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 con-
nected peripheral is turned on. Otherwise, the device automatically shuts
itself down drawing less than 1µA.
• ±8kV IEC1000-4-2 Contact
