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.
