The MAX3222E can be placed in the power-down mode by setting the power-down (PWRDOWN) input low,
which draws only 1
μ
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 enable (EN) high.

The device meets the requirements of TIA/EIA-232-F
and provides the electrical interface between an
asynchronous
communication
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/
μ
s driver output slew rate.
