3V-to-5.5V 250Kbps RS-485 transceiver with up to 3kV IEC surge and ±42V fault protection

THVD24x9 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 as well as small 10-pin VSON 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.

THVD24x9 devices in the standard pin-out SOIC package operate from a single 3.3V or 5V supply. In addition, THVD24x9 devices in 10-pin VSON package support an additional VIO supply to operate the IOs from as low as 1.65V 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.
