MAX232E (ACTIVE) Dual RS-232 Driver/Receiver with IEC61000-4-2 Protection


Recommended alternative parts

  • TRS232E  - The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device. 


The MAX232E is a dual driver and receiver that includes a capacitive voltage generator to supply RS-232-F compliant voltage levels from a single 5-V supply. Each receiver converts RS-232 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.
