FEATURES
■ Meets true EIA/TIA-232-F Standards
■ Minimum 120Kbps Data Rate Under Full
■ 1µA Low-Power Shutdown with Receivers
■ Interoperable with RS-232 down to +2.7V
■ Enhanced ESD Specifications:
Date: 02/24/05
The SP3222E/3232E series is an RS-232 transceiver solution intended for portable or hand-
held applications such as notebook or palmtop computers. The SP3222E/3232E 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/3232E series to deliver true RS-232
performance from a single power supply ranging from +3.3V to +5.0V. The SP3222E/3232E
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/3232E devices are
over ±15kV for both Human Body Model and IEC1000-4-2 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.
