3 Description
THVD1500 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 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.
THVD1500 is available in industry standard 8-pin
SOIC package for drop-in compatibility. The device is
characterized from –40°C to 125°C.
