The SP3222EB/3232EB series is an RS-232 transceiver solution intended for portable or
hand-held applications such as notebook or palmtop computers. The SP3222EB/3232EB
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/3232EB series to deliver true RS-
232 performance from a single power supply ranging from +3.0V to +5.5V. The SP3222EB/
3232EB 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 SP3222EB/
3232EB devices are over ±15kV for both Human Body Model and IEC1000-4-2 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
■ 250kbps Transmission Rate Under Load
■ 1µA Low-Power Shutdown with Receivers
■ Interoperable with RS-232 down to +2.7V
■ Enhanced ESD Specifications:
