High Speed +3.0V to +5.5V RS-232 Driver/Receiver Pair
SP3220EB/EU
DESCRIPTION
Meets True RS-232 Protocol Operation
From A +3.0V to +5.5V Power Supply
Minimum 250 Kbps Data Rate
(SP3220EB) or 1Mbps Data Rate
(SP3220EU) under Fully Load
1
A Low-Power Shutdown With
Receivers Active
Interoperable With EIA/TIA - 232 and
adheres to EIA/TIA - 562 Down to
+2.7V Power Source
Pin-Compatible With The
MAX3221E Device Without
The
AUTO ON-LINE
Feature
ESD Specifications:
+15kV Human Body Model
+15kV IEC1000-4-2 Air Discharge
+8kV IEC1000-4-2 Contact Discharge
The SP3220EB/EU device is an RS-232 driver/receiver solution intended for portable or hand-
held applications such as notebook or palmtop computers. The SP3220EB/EU device has a high-
efficiency, charge-pump power supply that requires only 0.1
F capacitors in 3.3V operation. This
charge pump allows the SP3220EB/EU device to deliver true RS-232 performance from a single
power supply ranging from +3.3V to +5.0V. The ESD tolerance of the SP3220EB/EUE device is
over 15kV for both Human Model and IEC1000-4-2 Air discharge test methods.
The SP3220EB/EU device has a low-power shutdown mode where the driver outputs and charge
pumps are disabled. During shutdown, the supply current falls to 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.
