■ Meets true EIA/TIA-232-F Standards
■ Interoperable with EIA/TIA-232 and
■ AUTO ON-LINE
■ Minimum 250kbps data rate under load
■ Regulated Charge Pump Yields Stable
■ Enhanced ESD Specifications:
The SP3223EB and SP3243EB products are RS-232 transceiver solutions intended for
portable or hand-held applications such as notebook and palmtop computers. The SP3223EB
and SP3243EB 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 SP3223EB/3243EB series to deliver compliant RS-232 performance from a single power
supply ranging from +3.0V to +5.5V. The SP3223EB is a 2-driver/2-receiver device, and the
SP3243EB is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA
applications. The SP3243EB 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.
