description/ordering information  
The MAX222 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). This 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. This device operates at data signaling rates up to 200 kbit/s and a maximum of 30-V/µs driver output  
slew rate. By using SHDN, all receivers can be disabled.
