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

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