Add To BomTHVD1449DR General Description
THVD14x9(V) devices are half-duplex RS-485 transceivers with integrated surge protection. Surge protection is achieved by integrating transient voltage suppressor (TVS) diodes in the standard 8-pin SOIC (D) package. This feature increases the reliability by providing better immunity to noise transients coupled to the data cable which eliminates the need for external protection components.
THVD1439 and THVD1449 operate from a single 3.3-V or 5-V supply. The THVD1439V and THVD1449V devices support an additional VIO supply to operate the IOs from as low as 1.65 V supply level. The devices in this family feature a wide common-mode voltage range making them suitable for multi-point applications over long cable runs.
