Design a Custom BoardAbout This Component
The MAX3232 is a dual RS-232 line driver and receiver IC for converting between 3.3V/5V logic and RS-232 serial signals. It integrates two drivers, two receivers, and an on-chip charge pump with ±15kV ESD protection, operating from a single 3V to 5.5V supply. Designed for portable and industrial applications requiring reliable serial communication at speeds up to 250 kbps.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
