Overview

Description

The MAX3233EEWP+ is a 3.0V to 5.5V RS-232 transceiver from Maxim Integrated (now part of Analog Devices). It features two drivers and two receivers, supporting data rates up to 250kbps.
Key features:
- Low power consumption (1µA shutdown mode).
- ±15kV ESD protection on I/O lines.
- Auto-shutdown to conserve power.
- Operates with minimal external components (only four 0.1µF capacitors needed).
Applications include industrial systems, embedded computing, and serial communication interfaces. The TSSOP-20 package makes it suitable for space-constrained designs.
A reliable choice for 3.3V or 5V systems requiring robust RS-232 communication.
