1 Overview

This document contains information for the ISO7741Tx-Q1 devices (ISO7741FTADWRQ1, ISO7741TADWRQ1, ISO7741FTBDWRQ1, and ISO7741TBDWRQ1) in the 16-DW SOIC 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 (pin FMA)

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

The ISO7741Tx-Q1 was developed using a quality-managed development process, but was not developed in accordance with the IEC 61508 or ISO 26262 standards.
