Product details

Dual-channel CAN FD transceiver for automotive networks

8 Mbps data rate and CAN FD compatibility

The 8 Mbps data rate is the key differentiator from classical CAN transceivers that top out at 1 Mbps. At this speed the part handles CAN FD payloads with the faster data phase, which is becoming standard in modern automotive ECUs for software updates and high-bandwidth sensor data. The receiver hysteresis of 100 mV provides noise immunity on the bus lines, reducing the risk of false bit detection in electrically noisy environments like a motor drive or engine bay.

The wettable flank feature means the side of the package has a plated surface that wets with solder, so an AOI system can verify the fillet — this is a requirement in many automotive tier-1 assembly specs where hidden solder joints under the package would otherwise be unverifiable.

Frequently asked questions

Is TCAN1046VDMTRQ1 compatible with CAN FD?

Yes. The TCAN1046VDMTRQ1 supports data rates up to 8 Mbps, which covers the CAN FD fast data phase. It handles both classical CAN and CAN FD frames without needing a protocol change at the transceiver level.

Does TCAN1046VDMTRQ1 have a wettable flank?

Yes. The 14-VSON package includes a wettable flank, which means the side terminations are plated to accept solder. This allows automated optical inspection (AOI) of the solder joints after reflow, a common requirement in automotive electronics assembly.

Can TCAN1046VDMTRQ1 replace TCAN1046V?

The TCAN1046VDMTRQ1 is a variant of the TCAN1046 base product number. The 'DM' suffix indicates a specific package and tape/reel configuration. Pin compatibility depends on the exact package variant — the TCAN1046VDMTRQ1 uses a 14-VSON with wettable flank, while other TCAN1046 variants may use a different package. Check the package drawing for footprint compatibility before substituting.

What is the lead time for TCAN1046VDMTRQ1?

Lead time is confirmed at quote time when you submit an RFQ. As an active-production part with no LTB or allocation flags, typical lead time is manageable through independent distribution channels. Submit an RFQ for current lead time and pricing.
