Interface

Renesas' enhanced ESD-protected RS-485/422 transceivers are designed for harsh environment applications where there is likely to be electrical noise or transients. These products meet all requirements of IEC 61000-4-2 and many have additional features such as electrical fast transient (EFT) immunity, low power, high-speed operation, hot plug capability, and more.
