The THVD1505 is a low-power RS-485 transceiver with automatic bus-polarity correction and transient protection. Upon hot plug-in, the device detects and corrects the bus polarity within the first 45 ms of bus idling. The bus pins are robust to electrostatic discharge (ESD) events, with high levels of protection to human-body model (HBM), IEC 61000-4-2 contact discharge and air-gap discharge specifications.

The device combines a differential driver and a differential receiver, which operate together from a single 5-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide common-mode voltage range making the device suitable for multi-point applications over long cable runs. The THVD1505 is available in an SOIC-8 package, and is characterized for free-air temperatures from –40°C to 125°C.
