说明 The MAX3232 device consists of two line drivers, two line receivers, 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. The devices operate at data signaling rates up to 250 kbit/s and a maximum of 30-V/µs driver output slew rate. 特性 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 Two Drivers and Two Receivers Low Supply Current... 300 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) SNx5C3232 Applications Battery-Powered Systems, PDAs, Notebooks, Laptops, Palmtop PCs, and Hand-Held Equipment Sipex SP3232 True +3.0V to +5.5V RS-232 Transceivers Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply n 235KBps Transmission Rate Under Load n 1mA Low-Power Shutdown with Receivers Active (SP3222E) n Interoperable with RS-232 down to +2.7V power source n Enhanced ESD Specifications: ±15kV Human Body Model ±15kV IEC1000-4-2 Air Discharge ±8kV IEC1000-4-2 Contact Discharge
