Texas Instruments MAX232

The MAX232 device is a dual driver/rece iver that includes a capacitive voltage generator to supply TIA/EIA-232-F volt age levels from a single 5-V supply. Ea ch receiver converts TIA/EIA-232-F inpu ts to 5-V TTL/CMOS levels. These receiv ers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Each driver conve rts TTL/CMOS input .

3 Description
The MAX232 device is a dual driver/receiver that
includes a capacitive voltage generator to supply
TIA/EIA-232-F voltage levels from a single 5-V
supply. Each receiver converts TIA/EIA-232-F inputs
to 5-V TTL/CMOS levels. These receivers have a
typical threshold of 1.3 V, a typical hysteresis of 0.5
V, and can accept ±30-V inputs. Each driver converts
TTL/CMOS input levels into TIA/EIA-232-F levels.
