SN65HVD1781QDRQ1

These devices combine a differential driver and a differential receiver, which operate from a single power supply. In the 'HVD1782, 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. This port features a wide common - mode voltage range, making the devices suitable for multipoint applications over long cable runs. These devices are characterized from -40°C to 125°C. These devices are pin - compatible with the industry - standard SN75176 transceiver, making them drop - in upgrades in most systems. These devices are fully compliant with ANSI TIA/EIA 485 - A with a 5 - V supply and can operate with a 3.3 - V supply with reduced driver output voltage for low - power applications.
