description/ordering information
The MAX3222 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 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 data signaling rates up to 250 kbit/s and a maximum
of 30-V/
s driver output slew rate.

description/ordering information (continued)
The MAX3222 can be placed in the power-down mode by setting PWRDOWN low, which draws only 1
A 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
V
CC
, and V- is raised toward GND. Receiver outputs also can be placed in the high-impedance state by setting
EN high.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to network GND.
2. Maximum power dissipation is a function of TJ(max),
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperature is PD = (TJ(max) - TA)/
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
3. The package thermal impedance is calculated in accordance with JESD 51-7.
