Analog Devices Inc./Maxim Integrated
2/2 Transceiver Full RS232 16-PDIP
Active4,307 in stock
Overview
The MAX232CPE+ is a dual RS-232 driver and receiver that operates from a single 5V supply. It utilizes internal charge pumps and four external 1.0uF capacitors to generate the necessary RS-232 voltage levels from standard logic levels.
Why Choose This Part
This part eliminates the need for a separate +/-12V power supply, simplifying board design by running entirely on 5V. Its 500 mV receiver hysteresis provides superior noise immunity in electrically noisy environments compared to standard logic gates.
Applications
Legacy Serial Interfacing
Connecting modern 5V microcontrollers to legacy RS-232 computer COM ports or industrial equipment.
Industrial Control Systems
Providing robust asynchronous communication between PLC units and peripheral sensors or terminals.
Breadboard Prototyping
The 16-DIP package allows for easy insertion into solderless breadboards for rapid firmware development and testing.
