MAX232E

具有 IEC61000-4-2 保护的双路 RS-232 驱动器/接收器

The is a dual driver and receiver that includes a capacitive voltage generator to supply RS-232-F compliant voltage levels from a single 5-V supply. Each receiver converts RS-232 inputs to 5-V TTL/CMOS levels. This receiver has 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 A/RS-232-F levels.
