The SN65HVD1781DR is a 70-V fault-protected RS-485 transceiver from Texas Instruments, designed to withstand harsh electrical conditions. It supports half-duplex communication with a signaling rate of up to 1 Mbps and operates with a supply voltage range of 3.15 V to 5.5 V.
This transceiver offers significant fault protection, rated for ±70 V on bus pins, making it suitable for applications prone to mis-wiring or overvoltage events. It also includes ±16 kV HBM ESD protection on bus pins. The device supports up to 320 nodes on the bus and features failsafe receivers for open-circuit, short-circuit, and idle-bus conditions.
Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, the SN65HVD1781DR operates within an industrial temperature range of -40°C to 125°C. Its low power consumption, with a maximum quiescent current of 4 mA and a standby supply current of 1 µA, makes it an efficient choice for various embedded systems.
The SN65HVD1781DR is pin-compatible with the industry-standard SN75176, facilitating upgrades and replacements in existing designs. Its robust design and comprehensive protection features make it ideal for industrial automation, building control, and other demanding communication environments.
