3.3V, 460 Kbps RS-232 Transceivers
SP3222EH/3232EH
DESCRIPTION
FEATURES
Meets true EIA/TIA-232-F Standards
from a +3.0V to +5.5V power supply
Interoperable with RS-232 down to +2.7V
power source
1
A Low-Power Shutdown with Receivers
Active (SP3222EH)
Enhanced ESD Specifications:
+
15kV Human Body Model
+
15kV IEC1000-4-2 Air Discharge
+
8kV IEC1000-4-2 Contact Discharge
460Kbps Minimum Transmission Rate
Ideal for Handheld, Battery Operated
Applications
The SP3222EH and the 3232EH are 2 driver/2 receiver RS-232 transceiver solutions
intended for portable or hand-held applications such as notebook or palmtop computers.
Their data transmission rate of 460Kbps meeting the demands of high speed RS-232
applications. Both ICS have a high-efficiency, charge-pump power supply that requires only
0.1
F capacitors for 3.3V operation. The charge pump allows the SP3222EH and the 3232EH
series to deliver true RS-232 performance from a single power supply ranging from +3.3V
to +5.0V. The ESD tolerance of the SP3222EH/3232EH devices exceeds
+
15kV for both
Human Body Model and IEC1000-4-2 Air discharge test methods.
The SP3222EH device has a low-power shutdown mode where the devices' driver outputs
and charge pumps are disabled. During shutdown, the supply current is less than 1
A.

NOTE 1: V+ and V- can have maximum magnitudes of 7V, but their absolute difference cannot exceed 13V.
ABSOLUTE MAXIMUM RATINGS
These are stress ratings only and functional operation of the
device at these ratings or any other above those indicated in
the operation sections of the specifications below is not
implied. Exposure to absolute maximum rating conditions
for extended periods of time may affect reliability and cause
permanent damage to the device.
