3-V TO 5.5-V MULTICHANNEL RS-232 LINE DRIVER/RECEIVER
WITH ±15-kV ESD PROTECTION
Check for Samples: MAX3222E
FEATURES
1
• ESD Protection for RS-232 Bus Pins
– ±15-kV Human-Body Model (HBM)
– ±8-kV IEC61000-4-2, Contact Discharge
– ±15-kV IEC61000-4-2, Air-Gap Discharge
• Meets or Exceeds the Requirements of
TIA/EIA-232-F and ITU v.28 Standards
• Operates With 3-V to 5.5-V VCC Supply
• Operates up to 500 kbit/s
• Two Drivers and Two Receivers
• Low Standby Current . . . 1 μA Typ
• External Capacitors . . . 4 × 0.1 μF
• Accepts 5-V Logic Input With 3.3-V Supply
• Alternative High-Speed Pin-Compatible Device
(1 Mbit/s) for SNx5C3222E
APPLICATIONS
• Battery-Powered Systems
• PDAs
• Notebooks
• Laptops
• Palmtop PCs
• Hand-Held Equipment
The device meets the requirements of TIA/EIA-232-F
and provides the electrical interface between an
asynchronous communication controller and the
serial-port connector. The charge pump and four
small external capacitors allow operation from a
single 3-V to 5.5-V supply. The device operates at
typical data signaling rates up to 500 kbit/s and a
maximum of 30-V/μs driver output slew rate.

DESCRIPTION/ORDERING INFORMATION
The MAX3222E consists of two line drivers, two line
receivers, and a dual charge-pump circuit with ±15-kV
ESD protection pin to pin (serial-port connection pins,
including GND).
The MAX3222E can be placed in the power-down mode by setting the power-down (PWRDOWN) input low,
which draws only 1 μA from the power supply. When the device is powered down, the receivers remain active
while the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is
disabled; V+ is lowered to VCC, and V– is raised toward GND. Receiver outputs also can be placed in the
high-impedance state by setting enable (EN) high.
