Product details

CANbus transceiver built for extreme heat — downhole, engine bay, defense

It comes in a hermetic 8-CFlatPack and is specified over -55°C to 210°C.

Hermetic CFP package — what it means for board assembly and reliability

The 8-CFlatPack (CFP) is a ceramic, hermetic package with leads formed for surface mounting. It is intended for high-reliability programs where outgassing, moisture ingress, and thermal cycling are deal-breakers.

210°C operating — not a typo, but know the limits

The -55°C to 210°C operating temperature range is the headline spec. 210°C junction is far beyond the 150°C or 175°C max of typical automotive CAN transceivers. This rating means the die is processed on a high-temperature fabrication flow (likely silicon-on-insulator or a specialty bipolar process) and assembled in a ceramic package that can handle the thermal expansion. Use it only where the environment demands it. The 140 mV receiver hysteresis is generous, giving good noise immunity on long or noisy bus lines at high temperature.

Frequently asked questions

Is SN65HVD233SHKJ compatible with 5V logic?

The CAN bus pins are differential and tolerate common-mode voltages beyond the supply, but the logic interface pins (TXD, RXD) are 3.3 V levels. Direct connection to a 5 V CAN controller may need level translation unless the controller has 3.3 V tolerant I/O.

Does SN65HVD233SHKJ come in a lead-free or RoHS package?

The 8-CFlatPack is a hermetic ceramic package. Hermetic packages typically use gold-plated Kovar leads and are not RoHS-exempt in the same way as plastic packages. Check the specific TI ordering code suffix for lead-free finish — the SHKJ suffix alone does not guarantee RoHS compliance. Request the TI material declaration for the exact date code.
