SP3223B/3243B

Intelligent +3.0V to +5.5V RS-232 Transceivers

■ 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 250kbps data rate under load

■ Regulated Charge Pump Yields Stable

RS-232 Outputs Regardless of V_CC

Variations

■ ESD Specifications:

+2kV Human Body Model

DESCRIPTION

The SP3223B and SP3243B products are RS-232 transceiver solutions intended for portable

or hand-held applications such as notebook and palmtop computers. The SP3223B and

SP3243B useaninternalhigh-efficiency, charge-pumppowersupplythatrequiresonly0.1µF

capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the

SP3223B/3243B series to deliver compliant RS-232 performance from a single power supply

ranging from +3.0V to +5.5V. The SP3223B is a 2-driver/2-receiver device, and the SP3243B

is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications. The

SP3243B includes one complementary receiver that remains alert to monitor an external

device's Ring Indicate signal while the device is shutdown.

TheAUTOON-LINE®featureallowsthedevicetoautomatically"wake-up"duringashutdown

statewhenanRS-232cableisconnectedandaconnectedperipheralisturnedon. Otherwise,

the device automatically shuts itself down drawing less than 1µA.
