1 / 16 page MAX211 5V MULTICHANNEL RS232 LINE DRIVER/RECEIVER WITH ±15kV ESD PROTECTION SLLS567E − MAY 2003 − REVISED JANUARY 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D RS-232 Bus-Pin ESD Protection Exceeds ±15 kV Using Human-Body Model (HBM) D Meets or Exceeds the Requirements of TIA/EIA-232-F and ITU v.28 Standards D Operates at 5-V VCC Supply D Four Drivers and Five Receivers D Operates Up To 120 kbit/s D Low Supply Current in Shutdown Mode ...1 µA Typical D External Capacitors ...4 × 0.1 µF D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II D Applications − Battery-Powered Systems, PDAs, Notebooks, Laptops, Palmtop PCs, and Hand-Held Equipment description/ordering information The MAX211 device consists of four line drivers, five 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 5-V supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/ µs driver output slew rate. The MAX211 has both shutdown (SHDN) and enable control (EN). In shutdown mode, the charge pumps are turned off, V+ is pulled down to VCC, V− is pulled to GND, and the transmitter outputs are disabled. This reduces supply current typically to 1 µA. EN is used to put the receiver outputs into the high-impedance state to allow wired-OR connection of two RS-232 ports. It has no effect on the RS-232 drivers or the charge pumps.
