MAX232CPE+

MAX232CPE+ - Dual RS232 Driver/Receiver Transceiver IC

The MAX232CPE+ from Analog Devices Inc./Maxim Integrated is a dual RS232 driver/receiver transceiver that converts TTL/CMOS logic levels to RS232 voltage levels and vice versa. This industry-standard communication interface IC is essential for serial communication applications requiring reliable data transmission between microcontrollers, computers, and peripheral devices.

Key Features & Benefits

• Dual Transceiver Configuration: 2 drivers and 2 receivers for complete bidirectional communication
• Full Duplex Operation: Simultaneous transmit and receive capability for efficient data transfer
• RS232 Protocol Support: Industry-standard serial communication interface
• 120Kbps Data Rate: Fast and reliable data transmission for most serial applications
• 500mV Receiver Hysteresis: Enhanced noise immunity for robust signal integrity
• Single 5V Supply: Operates from 4.5V to 5.5V with integrated charge pump for RS232 voltage generation
• Through-Hole Package: Easy prototyping and reliable mechanical connection in 16-DIP format
• RoHS Compliant: Lead-free and environmentally friendly manufacturing

Common Applications

The MAX232CPE+ is widely used in various serial communication applications:

• Microcontroller to PC serial communication interfaces
• Industrial automation and control systems
• Point-of-sale (POS) terminals and barcode scanners
• Modem and telecommunications equipment
• Embedded systems requiring RS232 connectivity
• Legacy equipment interface and protocol conversion
• Test and measurement instrumentation
• Data acquisition systems

Design Advantages

The MAX232 family has been the go-to solution for RS232 level conversion for decades due to its simplicity and reliability. With integrated charge pump capacitors, this IC generates the necessary ±10V RS232 voltage levels from a single 5V supply, eliminating the need for dual power supplies. The through-hole DIP package makes it ideal for breadboard prototyping, educational projects, and applications where socketed components are preferred for easy replacement.
