................................................................................................................................................ SLLS596C – OCTOBER 2003 – REVISED AUGUST 2009

5-V MULTICHANNEL RS-232 LINE DRIVER/RECEIVER

WITH ± 15-kV ESD PROTECTION

• ESD Protection for RS-232 I/O Pins

– ± 15-kV Human-Body Model (HBM)

• Meets or Exceeds the Requirements of

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

• Operates at 5-V V

Supply

• Four Drivers and Four Receivers

• Operates up to 120 kbit/s

• External Capacitors: 4 × 0.1 µ F

• Latch-Up Performance Exceeds 100 mA Per

JESD 78, Class II

• Battery-Powered Systems

• Hand-Held Equipment

The MAX208 device consists of four line drivers, four line receivers, and a dual charge-pump circuit with ± 15-kV

HBM 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 5-V

supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/ µ s driver output

slew rate.

The MAX208 requires 0.1-µF capacitors, although capacitors up to 10 µF can be used without harm. Ceramic dielectrics are suggested for the 0.1-µF capacitors.
