The UPD720114GA-9EU-A is a Renesas Electronics SIP package dual 4-channel RS-485 differential line transciever. This device is especially designed for difficult transmission environments found in industrial control networks such as Profibus, International Standardization Organization (ISO), ISometers, Expanded Industrial Standard Architecture (EISA), Industrial Standard Architecture (ISA), and Network Resources Management (NRM). It features built-in electrostatic discharge (ESD) protection, high signal integrity, and signal isolation. This makes it ideal for use with noise-sensitive systems, such as those found in industrial automation and process control systems.
