description
The MAX232 is a dual driver/receiver that
includes a capacitive voltage generator to supply
EIA/TIA-232-E voltage levels from a single 5-V
supply. Each receiver converts EIA/TIA-232-E
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/TIA-232-E levels. The driver, receiver, and
voltage-generator functions are available as cells
in the Texas Instruments LinASIC library.
The MAX232 is characterized for operation from
0°C to 70°C. The MAX232I is characterized for
operation from –40°C to 85°C.
