Renesas Electronics Corporation has introduced the RAA78815x Family of 5V differential RS-485/422 transceivers with high output drive and additional immunity for EFT. These six new full and half duplex ruggedized devices with ESD protection up to ±16,000V are the ideal solution for noise-sensitive industrial communication networks and meet both the RS-485 and RS-422 communication standards. These Transceivers are suited for a variety of industrial network, process control network, building automation, long-haul network, and security camera network applications.
These new high-speed transceivers feature bus leakage currents of maximum 125 μA thereby, constituting a true 1/8-unit load and support data rates of 115kbps, 1Mbps, and 20Mbps with a performance that is characterized from -40°C to +85°C. With EFT immunity of ±5000V, the RAA78815x family delivers exceptional differential output voltages, featuring 3.1V into the RS-485-required 54Ω load.
