MAX232 IC RS-232 Line Driver/Receiver

MAX232 IC — RS-232 Line Driver/Receiver

The MAX232 IC by Maxim Integrated is a widely used RS-232 line driver/receiver that converts TTL/CMOS logic levels to RS-232 voltage levels and vice versa. It enables microcontrollers and TTL devices to communicate directly with PC serial ports using a single +5V supply.

Key Features

• Single +5V power supply operation
• Output voltage swing up to ±7.5V
• Dual drivers and dual receivers
• 16-pin DIP package and multiple other packages
• Internal charge pumps — requires only four 1µF external capacitors

Applications

• Microcontroller UART to PC RS-232 serial port conversion
• TTL to RS-232 voltage level conversion
• Industrial serial communication interfaces
• Embedded systems serial debugging
