Overview
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 highefficiency, 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 Discharge Ordering Information - Page 21 Typical Applications VCC + C5 0.
