SP3222E/SP3232E
True +3.0V to +5.5V RS-232 Transceivers
The
SP3222E/SP3232E series is an RS-232 transceiver solution intended for portable or
hand-held applications such as notebook or palmtop computers. The
SP3222E/SP3232E
series has a high-efficiency, charge-pump power supply that requires only 0.1F capaci-
tors in 3.3V operation. This charge pump allows the
SP3222E/SP3232E series to deliver
true RS-232 performance from a single power supply ranging from +3.0V to +5.5V. The
SP3222E/SP3232E are 2-driver/2-receiver devices. This series is ideal for portable or
hand-held applications such as notebook or palmtop computers. The ESD tolerance of the
SP3222E/SP3232E devices are over +/-15kV for both Human Body Model and IEC61000-4-2
Air discharge test methods. The
SP3222E 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 1A.
FEATURES
■ Meets true EIA/TIA-232-F Standards
from a +3.0V to +5.5V power supply
■ Minimum 120kbps Data Rate Under Full
Load
■ 1A Low Power Shutdown with
Receivers active (
SP3222E)
■ 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
