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 VCC, and V– is raised toward GND. Receiver outputs also can be placed in the  
high-impedance state by setting enable (EN) high.
