2.2.5 THVD1500

The THVD1500 device 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 of additional system-level protection components.

The device operates from a single 5-V supply. The wide common-mode voltage range and low input leakage on bus pins make THVD1500 suitable for multi-point applications over long cable runs.

The THVD1500 device is available in industry standard 8-pin SOIC package for drop-in compatibility. The device is characterized from –40°C to 125°C. The device also meets or exceeds the requirements of the TIA/EIA-485A Standard and the State Grid Corporation of China (SGCC) Part 11 Serial Communication Protocol RS-485 Standard.

This device is specifically used in this design to convert from UART to RS-485 signals.
