MAX232N, Двухканальный приемопередатчик интерфейса RS-232
The MAX232N is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. These receivers have a typical threshold of 1.3V, a typical hysteresis of 0.5V, and can accept ±30V 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.
• Operates from a single 5V power supply with 1µF charge pump capacitors
• Operates up to 120kbit/s
• Two drivers and two receivers
• ±30V input levels
• Low supply current: 8mA typ.
