RS232 to TTL Converter (MAX232) AND gate floors and doorsIntroduction : RS232 to TTL Converter (MAX232) is widely used in the world of microcontrollers. It basically allows shifting levels between a TTL signal (0 5 V) and a RS232 signal (15 V 15 V). Its built around the MAX232 IC, which is designed specifically for that purpose, needing only four external capacitors to generate a higher voltage internally. Features : Operating Voltage: 3V to 5. 5V. Can work with 5V and 3. 3V logic devices. Operating
