Description

The MAX3221CDBG4 consists of one line driver, one line receiver, 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 kbit/s and a maximum of 30-V/μs driver output slew rate. MAX3221CDBG4 Features • RS-232 Bus-Pin ESD Protection Exceeds ±15 kV Using Human-Body Model (HBM)• Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards• 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 μA Typical• External Capacitors . . . 4 × 0.1 μF• Accepts 5-V Logic Input With 3.3-V Supply• Alternative High-Speed Pin-Compatible Device (1 Mbit/s)− SNx5C3221• Auto-Powerdown Feature Automatically Disables Drivers for Power Savings
