SP3222EB / SP3232EB
Data Sheet
True +3.0V to +5.5V RS-232 Transceivers
General Description
The SP3222EB and SP3232EB series are RS-232
transceiver solutions intended for portable or hand-held
applications such as notebook or laptop computers. The
SP3222EB / SP3232EB series has a high-efficiency,
charge-pump power supply that requires only 0.1µF
capacitors in 3.3V operation. This charge pump allows the
SP3222EB / SP3232EB series to deliver true RS-232
performance from a single power supply ranging from
3.0V to 5.5V. The SP3222EB / SP3232EB are 2-driver /
2-receiver devices. The ESD tolerance of the SP3222EB /
SP3232E devices is over ±15kV for both Human Body
Model and IEC61000-4-2 Air discharge test methods. The
SP3222EB device has a low-power shutdown mode
where the devices’ driver outputs and charge pumps are
disabled. During shutdown, the supply current falls to less
than 1µA.
Features
Meets true EIA / TIA-232-F standards from a 3.0V to
5.5V power supply
250kbps transmission rate under load
1μA low power shutdown with receivers active
(SP3222EB)
Interoperable with RS-232 down to a 2.7V power source
Enhanced ESD specifications:
 ±15kV Human Body Model
 ±15kV IEC61000-4-2 Air Discharge
 ±8kV IEC61000-4-2 Contact Discharge
