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 V

, and V– is raised toward GND. Receiver outputs also can be placed in the

high-impedance state by setting enable (EN) high.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
