Product details

25 Mbps full-duplex transceiver for industrial RS-485/RS-422 links

It delivers 25 Mbps signaling, making it a fit for high-speed factory automation, motor drive feedback, and building automation networks where the bus must keep up with fast sensor or encoder data.

Industrial temperature rating and supply rail

It runs from a 5V supply rail (4.5V to 5.5V), so the board already has a 5V bus — no extra regulator needed for the interface side.

Receiver hysteresis and driver/receiver count

Built-in 50 mV receiver hysteresis rejects noise on long cable runs, reducing the chance of false triggering from ground shifts or coupled interference. The 1/1 driver/receiver count is the standard for a single full-duplex node — one driver for the transmit pair, one receiver for the receive pair.

For a production BOM, that means the supply channel stays open through normal distribution without the sourcing scramble that comes with an NRND or obsolete part.

Frequently asked questions

What is the data rate of SN65HVD179D?

The SN65HVD179D supports a data rate of 25 Mbps. That is fast enough for Profibus, Modbus RTU at high baud rates, and encoder feedback links that push past the 10-12 Mbps ceiling of older transceivers.
