SN65HVD08D Description

The SN65HVD08D from Texas Instruments is a robust half-duplex RS-422/RS-485 transceiver designed for reliable data communication in industrial and automotive environments. Housed in an 8-pin SOIC package, this surface-mount IC integrates one driver and one receiver, supporting bidirectional data transmission over long distances with minimal signal degradation. Operating from a 3V to 5.5V supply, it ensures compatibility with both 3.3V and 5V systems. The device features 35 mV of receiver hysteresis, enhancing noise immunity in electrically noisy environments. With REACH Unaffected and ROHS3 Compliant certifications, it meets stringent environmental and safety standards.
