3.3V RS-485/RS-422 Transceiver IC with High ESD Protection for Multi-Node Industrial Communication
The SP3072EEN-L/TR is a high-performance RS-485/RS-422 transceiver designed for reliable bidirectional communication over differential bus networks. Manufactured by MaxLinear, this device integrates a differential driver and receiver, making it suitable for multipoint communication systems in industrial and embedded applications.
Operating from a 3.3 V supply, the SP3072EEN-L/TR features high receiver input impedance, allowing multiple transceivers to share a single communication bus without excessive loading. The device offers robust protection features including thermal shutdown, short-circuit protection, and high ESD immunity up to 15 kV. With fail-safe receiver operation and a wide common-mode voltage range from 7 V to +12 V, it ensures stable and reliable communication even in electrically noisy environments.
