Product details

26 Mbps full-duplex RS-485 transceiver in 8-SOIC

Typical deployment is in industrial automation, building control, and networked sensor buses where differential signaling over twisted-pair cabling is required.

The transceiver's logic inputs are compatible with 3.3 V CMOS levels, so no external level shifter is needed when driving from a 3.3 V UART or controller. The 50 mV hysteresis on the receiver input helps reject noise on differential lines, reducing bit errors in electrically noisy environments like motor drives or factory floors.

This makes it suitable for PLC I/O modules, HVAC controllers, and remote terminal units where the ambient temperature stays within that band.

Frequently asked questions

Is SN65HVD30DRG4 compatible with 3.3 V logic?

Yes.

What is the difference between SN65HVD30DRG4 and SN65HVD30DR?

The DRG4 suffix indicates a specific tape-and-reel packaging variant and RoHS compliance level; the electrical specifications are the same.

Is SN65HVD30DRG4 obsolete?

No.
