MAX488ECSA

MAX488ECSA Description

The MAX488ECSA 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-pin SOIC package, this surface-mount IC operates within a 4.75V to 5.25V supply range and supports data rates up to 250kbps. It integrates one driver and one receiver, making it ideal for bidirectional communication in industrial, automotive, and embedded systems. With 70mV receiver hysteresis, it ensures reliable signal integrity in noisy environments. The device is REACH compliant and classified under ECCN EAR99, suitable for global deployment.

MAX488ECSA Features
