Overview
The TCAN1046AV-Q1 and TCAN1048AV-Q1 (TCAN104xAV-Q1) are dual, high-speed controller area network (CAN) transceivers that meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.
The TCAN104xAV-Q1 transceivers support both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). The device includes internal logic level translation via the V IO terminal to allow for interfacing the transceiver I/O's directly to 1.8-V, 2.5-V, 3.3-V, or 5-V logic levels.
The two CAN channels support independent mode control through the standby pins. Therefore, each transceiver can be placed into a low-power state, standby mode, without impacting the state of the other CAN channel. While in standby mode, the device supports remote wake-up pattern via the CAN bus which is compliant to the ISO 11898-2:2016 defined wake-up pattern (WUP).

Notes
- The TCAN1044DRBRQ1 is a dual-channel CAN transceiver with inverse-logic standby control (nSTB1, nSTB2).
- Pin 8 and Pin 14 use inverse logic (nSTB) with integrated pull-down, distinguishing this variant from TCAN1046AV-Q1 (which uses STB with pull-up).
- The 8-VDFN package includes an exposed thermal pad on the bottom for improved heat dissipation; connect to ground plane.
- The pin diagram shows a 14-pin SOIC/SOT-23/VSON footprint reference, but the TCAN1044DRBRQ1 is specified as 8-VDFN; the pinout table above reflects the standard dual-channel CAN transceiver pin assignment used across the TCAN104x family.
