Product details

High-temperature RS-485 transceiver in a hermetic package

This makes it a go-to choice for downhole drilling, engine bay electronics, aerospace, and other high-temperature or sealed-enclosure applications where reliability at extreme temperature is non-negotiable.

10 Mbps data rate and 3.3V supply rail

The transceiver supports data rates up to 10 Mbps over RS-485 or RS-422 networks, sufficient for industrial fieldbus, sensor links, and actuator control loops.

Active lifecycle — still in production, no LTB risk

It is not nearing end-of-life, not on last-time-buy, and remains a current-production catalog item.

Hermetic 8-CFP package — what it means for assembly

The 8-CFlatPack is a ceramic, hermetic surface-mount package. Unlike plastic SOIC packages, the ceramic body and lid seal the die against moisture and corrosive atmospheres. The trade-off is cost and assembly — ceramic packages are more expensive and may require different solder profiles than standard FR-4 reflow.

Sourcing this part — quoted to order

Because it is an active, current-production TI part, supply is generally stable, but the hermetic package means it is less commonly stocked in high volume than its plastic-packaged siblings — lead times may vary and should be confirmed at order.

Frequently asked questions

Can SN65HVD11SHKJ be used with 3.3V only, or does it support 5V logic?

It is a 3.3V transceiver. The logic inputs are not rated for 5V tolerance, so if the host controller uses 5V logic, external level shifters are required.
