Product details

Active production, AEC-Q100 qualified CAN transceiver

5V supply rail only — plan the power tree accordingly

It is not compatible with 3.3 V logic supplies on the bus side; if the host controller runs at 3.3 V, a level translator or a 3.3 V-tolerant CAN transceiver variant is needed. The VCC pin must be cleanly decoupled to the exposed pad ground plane to maintain signal integrity at 5 Mbps.

Package and footprint notes for the layout review

The device is supplied in an 8-VDFN with exposed pad (8-VSON 3x3 mm). The wettable flank option on this package aids automated optical inspection (AOI) after reflow, a common requirement in automotive assembly lines.

It is ROHS3 compliant.

Frequently asked questions

Is TCAN1042DRBTQ1 compatible with 5V CAN bus only?

Yes. It is not compatible with 3.3 V logic on the bus side without external level shifting.

What is the closest pin-compatible alternative to TCAN1042DRBTQ1 in this component family?

The TCAN1042 family includes multiple variants with different package options and temperature grades. The TCAN1042DRQ1 is a similar 8-SOIC variant, but pin compatibility depends on the package footprint. For a direct drop-in in the same 8-VSON package, the TCAN1042VDRBTQ1 adds a VIO pin for 3.3 V logic interface. Verify the pinout against your design before substituting.
