MAX483EPA

MAX483EPA Description

The MAX483EPA from Analog Devices Inc./Maxim Integrated is a half-duplex RS-422/RS-485 transceiver designed for robust serial communication in industrial and embedded systems. Housed in an 8-pin DIP (Through Hole) package, this IC integrates one driver and one receiver, supporting data rates up to 250kbps. Operating within a 4.75V to 5.25V supply range, it features 70mV receiver hysteresis for enhanced noise immunity, making it suitable for electrically noisy environments. The device complies with ECCN 5A991G and is REACH unaffected, ensuring global usability. Although marked obsolete, it remains a reliable choice for legacy systems due to its proven performance.
