MAX488EESA Description

The MAX488EESA from Analog Devices Inc./Maxim Integrated is a full-duplex RS-422/RS-485 transceiver designed for robust differential data communication. Housed in an 8-SOIC package, it integrates one driver and one receiver, supporting data rates up to 250kbps. Operating within a 4.75V to 5.25V supply range, it is optimized for low-power applications while ensuring reliable signal integrity. The device features 70mV receiver hysteresis, enhancing noise immunity in electrically noisy environments. With an EAR99 ECCN classification and REACH compliance, it meets global regulatory standards. Though marked obsolete, it remains a viable choice for legacy systems due to its proven performance.
