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/
μ
s driver
output slew rate.
