NOS8005 RS485 Interface

NOS8005 is a half-duplex RS-485 transceiver built for challenging industrial environments supporting data rates up to 500kbps and a wide common-mode voltage between -15V and +15V. The module offers rugged input protection against IEC electrical fast transients (EFT) and IEC electrostatic discharge(ESD) events with +/- 30kV ESD contact and air-gap protection.

Additionally, an accurate auto-direction circuit eliminates the need to control directivity via software
