Max232 Dual Driver and Receiver

Description of Max232 Dual Driver and Receiver 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.   Features Meet or Exceed TIA/EIA-232-F and ITU Recommended V.28 Operates From a Single 5-V Power Supply With 1.0-µF Charge-Pump Capacitors Operate Up To 120 kbit/s Two Drivers and Two Receivers ±30-V Input Levels Low Supply Current ...8 mA Typical ESD Protection Exceeds JESD 22 2000-V Human-Body Model (A114-A) Upgrade With Improved ESD (15-kV HBM) and 0.1-µF Charge-Pump Capacitors is Available With the MAX202 Applications TIA/EIA-232-F, Battery-Powered Systems, Terminals, Modems, and Computers
