SLLS723C – APRIL 2006 – REVISED AUGUST 2016 MAX232E Dual RS-232 Driver and Receiver With IEC61000-4-2 Protection
1 Features 3 Description The MAX232E is a dual driver and receiver that
includes a capacitive voltage generator to supply RS232-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 В±30-V inputs. Each driver converts
TTL/CMOS input levels into TIA/RS-232-F levels. 1 Meets or Exceeds TIA/RS-232-F and ITU
Recommendation V.28
