The THVD1400 is a robust half-duplex RS-485 transceiver for industrial applications. The bus pins are immune to high levels of IEC Contact Discharge ESD events, eliminating the need for additional system-level protection components due to ±12-kV IEC 61000-4-2 contact discharge bus I/O protection. The device operates from a single 3- to 5.5-V supply and is available in industry standard, 8-pin SOIC package for drop-in compatibility as well as in the industry-leading, small SOT package.
The device is characterized for ambient temperatures from –40°C to 125°C and also meets or exceeds the requirements of the TIA/EIA-485A standard. The wide common-mode voltage range and low input leakage on bus pins make the devices an excellent choice for multi-point applications over long cable runs.
This device is specifically used in this design to convert from UART to RS-485 signals.
