SP3222E / SP3232E
True 3.0V to 5.5V RS-232 Transceivers
Description
The
SP3222E
and
SP3232E
series are RS-232 transceiver solutions
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 0.1µF
capacitors 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 1µA.
FEATURES
Meets true EIA/TIA-232-F standards from
a 3.0V to 5.5V power supply
Minimum 120kbps data rate under full load
1μA 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
