This document contains information for the TCAN1043N-Q1 and TCAN1473-Q1 to aid in a functional safety system design. This is a controller area network (CAN) transceiver in the SOIC (D), VSON (DMT), and SOT (DYY) packages to aid in a functional safety system design. Information provided are:

• Functional safety failure in time (FIT) rates of the semiconductor component estimated by the application of industry reliability standards
• Component failure modes and their distribution (FMD) based on the primary function of the device
• Pin failure mode analysis (FMA) for the device pins of TCAN1043N-Q1 and TCAN1473-Q1

Figure 1-1 shows the device functional block diagram for reference.

TCAN1043N-Q1 and TCAN1473-Q1 were developed using a quality-managed development process, but were not developed in accordance with the IEC 61508 or ISO 26262 standards.
