MAX3221CPWR Product Details
The MAX3221CPWR device consists of one line driver, one line receiver with dedicated enable pin, 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 kbps and a maximum of 30-V/±s driver output slew rate.
Flexible control options for power management are available when the serial port is inactive. The automatic power-down feature functions when FORCEON is low and INVALID output notifies the user if an RS-232 signal is present at the receiver input.
