MAX232, MAX232I DUAL EIA-232 DRIVERS/RECEIVERS SLLS047I – FEBRUARY 1989 – REVISED OCTOBER 2002 1 POST OFFICE BOX 655303 DALLAS, TEXAS 75265 D Meet or Exceed TIA/EIA-232-F and ITU Recommendation V.28 D Operate With Single 5-V Power Supply D Operate Up to 120 kbit/s D Two Drivers and Two Receivers D ± 30-V Input Levels D Low Supply Current. ..8mATypical D Designed to be Interchangeable With Maxim MAX232 D ESD Protection Exceeds JESD 22 2000-V Human-Body Model (A114-A) D Applications TIA/EIA-232-F Battery-Powered Systems Terminals Modems Computers description/ordering information The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232 voltage levels from a single 5-V supply. Each receiver converts EIA-232 inputs to 5-V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V and a typical hysteresis of 0.5 V, and can accept ± 30-V inputs. Each driver converts TTL/CMOS input levels into EIA-232 levels. The driver, receiver, and voltage-generator functions are available as cells in the Texas Instruments LinASIC library.
