The MAX3221E is a single driver, single receiver
RS-232 solution operating from a single VCC 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 3V to 5.5V supply. These
devices operate at data signaling rates up to 250kbit/s and a maximum of 30V/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.
