description/ordering information
The MAX211
device consists of four line drivers, five 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 5-V supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/
s
driver output slew rate.
The MAX211 has both shutdown (SHDN) and enable control (EN). In shutdown mode, the charge pumps are
turned off, V+
is pulled down to V
CC
, V is pulled to GND, and the transmitter outputs are disabled. This
reduces supply current typically to 1
A. EN is used to put the receiver outputs into the high-impedance state
to allow wired-OR connection of two RS-232 ports. It has no effect on the RS-232 drivers or the charge pumps.

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.
