description
The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232
voltage levels from a single 5-V supply. Each receiver converts EIA-232 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-232 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.
