Product details

Half-duplex RS-485 transceiver with wide supply tolerance

Its 3V to 5.5V supply range lets it bridge 3.3V controllers to 5V legacy bus networks without a separate level shifter — a common requirement in industrial sensor busses and building-automation panels. The 35 mV receiver hysteresis provides enough noise margin for runs up to a few hundred metres at moderate data rates, typical for factory-floor Modbus or BACnet links.

Lifecycle — still an active production part

TI lists the SN65HVD08DRG4 as Active.

Frequently asked questions

Is SN65HVD08DRG4 compatible with 5V supply?

Yes, the 3V to 5.5V supply range includes 5V directly — no external regulator needed.

What is the closest alternative for SN65HVD08DRG4?

The SN65HVD08DR is the same die in a tube or reel variant; the DRG4 suffix indicates TI's green (RoHS) packaging. For a pin-compatible second source, consider the Maxim MAX1487 or the ADI ADM485, both half-duplex RS-485 transceivers in 8-SOIC with similar supply ranges.
