3 Description
The MAX3221E is a single driver, single receiver RS-
232 solution operating from a single V
CC
supply. The
RS-232 pins provide IEC 61000-4-2 ESD protection.
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.
Flexible control options for power management are
available. Auto-power down disables driver and
charge pump when the receiver is disconnected or
the remote driver is power down. The drivers can be
manually enabled or disabled. INVALID output goes
low when receiver input is unconnected or power off.
