WITH ± 15-kV IEC ESD PROTECTION

• Qualified for Automotive Applications

• Meets or Exceeds the Requirements of

TIA/EIA-232-F and ITU v.28 Standards

• Operates With 3-V to 5.5-V V

Supply

• Operates up to 250 kbit/s

• Two Drivers and Two Receivers

• Low Standby Current . . .300 µ A Typical

• External Capacitors . . . 4 × 0.1 µ F

• Accepts 5-V Logic Input With 3.3-V Supply

• Pin Compatible to Alternative High-Speed

Pin-Compatible Device (1 Mbit/s): SNx5C3232

The MAX3232E device consists of two line drivers, two line receivers, and a dual charge-pump circuit with

± 15-kV IEC 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 device operates at data signaling rates up to 250 kbit/s and a maximum of

30-V/ µ s driver output slew rate.
