– SNx5C3221  
(1) Component qualification in accordance with JEDEC and  
industry standards to ensure reliable operation over an  
extended temperature range. This includes, but is not limited  
to, Highly Accelerated Stress Test (HAST) or biased 85/85,  
temperature cycle, autoclave or unbiased HAST,  
electromigration, bond intermetallic life, and mold compound  
life. Such qualification testing should not be viewed as  
justifying use of this component beyond specified  
performance and environmental limits.  
DESCRIPTION/ORDERING INFORMATION  
The MAX3221 consists of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV ESD  
protection pin to pin (serial-port connection pins, including GND). The 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 3-V to  
5.5-V supply. These devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver  
output slew rate.
