What are the key specifications?

It supports a 120 kbps data rate, operates from 4.5V to 5.5V, and includes two drivers and two receivers in a 16-pin SOP package.

What should engineers review before using this part?

Verify the charge pump capacitor requirements (0.1µF) and ensure the layout minimizes noise, as the internal charge pump switches at high frequencies.

What are the sourcing risks?

The part is widely available, but users should verify the specific ESD requirements of their application, as ±2kV may be insufficient for exposed ports.

What is the pinout of MAX232ESE?

Use the MAX232ESE datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about MAX232ESE pinout to locate pins, power rails, and interface signals before layout.
