SN65HVD1780QDRQ1 TI RS-485 Transceiver | 8-SOIC | 3.3V/5V, 70V Fault Protection

Product Overview

The SN65HVD1780QDRQ1 is a robust RS-485/RS-422 transceiver from Texas Instruments, designed for industrial and automotive applications requiring reliable communication in harsh environments. It features a wide supply voltage range (3V to 5.5V) and offers up to ±70V fault protection on the bus pins, making it ideal for systems where ground potential differences or transient overvoltages are common. The device supports data rates up to 1 Mbps and is available in an 8-pin SOIC package. It is qualified for automotive applications (AEC-Q100).
