MAX3221EIPWR Datasheet

RS-232 Interface IC


The MAX3221EIPWR is a single driver, single receiver RS-232 solution operating from a single VCC 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/ms driver output slew rate. MAX3221EIPWR Features • Operates With 3-V to 5.5-V VCC Supply• Operates up to 250 kbit/s• One Driver and One Receiver• Low Standby Current . . . 1 mA Typ• External Capacitors . . . 4 ´ 0.1 mF• Accepts 5-V Logic Input With 3.3-V Supply• Alternative High-Speed Pin-Compatible Device (1 Mbit/s) – SN75C3221E and SN65C3221E• Auto-Powerdown Feature Automatically Disables Drivers for Power Savings MAX3221EIPWR Applications • Battery-Powered, Hand-Held, and Portable Equipment• PDAs and Palmtop PCs• Notebooks, Subnotebooks, and Laptops• Digital Cameras• Mobile Phones and Wireless Devices
