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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to network ground terminal.
