3-V TO 5.5-V SINGLE-CHANNEL RS-232 LINE DRIVER/RECEIVER WITH ??15-kV IEC ESD PROTECTION

The TRS3221E is a single driver, single receiver RS-232 solution operating from a single V CC supply. The RS-232 pins provide IEC G1000-4-2 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/ s driver output slew rate. By Texas Instruments
