Datasheet
 

Recommended alternative parts

  • MAX232E  -  TI recommends MAX232E in new designs. The MAX232E is an improved direct drop-in replacement for the MAX232
  • MAX3232E  -  This device has an extended Vcc range (3V), a higher data rate and IEC 61000-4-2 protection.
  • MAX3232  -  This device has an extended Vcc range (3V), a higher data rate.

Description

The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-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.
