Dual EIA-232 Driver/Receiver - MAX232

MAX232 (ACTIVE)

Dual EIA-232 Driver/Receiver

Recommended alternative parts

  • TRS232E  -  The device has the SAME FUNCTIONALITY/PINOUT as the compared device but includes enhanced IEC61000-4-2 ESD Protection.
  • MAX232E  -  TI recommends MAX232E in new designs. The MAX232E is an improved direct drop-in replacement for the MAX232
  • TRS232  - The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device. 

Description

The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5-V TTL/CMOS levels. These receivers have 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/EIA-232-F levels. The driver, receiver, and voltage-generator functions are available as cells in the Texas Instruments LinASIC™ library.
