SLLS791C – JUNE 2007 – REVISED SEPTEMBER 2008 DUAL RS-232 DRIVER/RECEIVER WITH IEC61000-4-2 PROTECTION 2 • Meets or Exceeds TIA/RS-232-F and ITU Recommendation V.28 • Operates From a Single 5-V Power Supply With 1.0- µF Charge-Pump Capacitors • Operates up to 250 kbit/s • Two Drivers and Two Receivers • ±30-V Input Levels • Low Supply Current . . . 8 mA Typical • ESD Protection for RS-232 Bus Pins – ±15-kV Human-Body Model (HBM) – ±8-kV IEC61000-4-2, Contact Discharge – ±15-kV IEC61000-4-2, Air-Gap Discharge • TIA/RS-232-F • Battery-Powered Systems • Terminals • Modems • Computers The TRS232E is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/RS-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/RS-232-F inputs to 5-V TTL/CMOS levels. This receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Each driver converts TTL/CMOS input levels into TIA/RS-232-F levels. The driver, receiver, and voltage-generator functions are available as cells in the Texas Instruments LinASIC™ library. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 LinASIC is a trademark of Texas Instruments.
