description/ordering information
The MAX232 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. The driver, receiver, and
voltage-generator functions are available as cells in the Texas Instruments LinASIC library.
