MAX232N Pinout

The MAX232N is a dual driver/receiver IC designed to convert TTL logic levels to RS-232 signal levels, and vice versa. It is commonly used in serial communication applications where a microcontroller or TTL device needs to communicate with RS-232 devices. The chip features 16 pins, including charge pump capacitor connections, two transmitters (T1, T2), and two receivers (R1, R2), as well as power and ground pins. This pin configuration ensures proper signal translation and reliable communication.

Understanding the MAX232N pin configuration is essential for implementing RS-232 level translation in embedded systems. Each pin has a specific role in voltage generation, signal input/output, or power management. When connected correctly, the MAX232N enables seamless data exchange between TTL-level logic and RS-232 compliant devices.
