3 Failure Mode Distribution (FMD)

The failure mode distribution estimation for SN74LVC2G17-Q1 in Table 3-1 comes from the combination of common failure modes listed in standards such as IEC 61508 and ISO 26262, the ratio of sub-circuit function size and complexity and from best engineering judgment.

The failure modes listed in this section reflect random failure events and do not include failures due to misuse or overstress.

Table 3-1 Die Failure Modes and Distribution
Die Failure Modes Failure Mode Distribution (%)
Driver output stuck-at fault 20%
Output open (HiZ) 20%
Output functional – out of specification timing or voltage 40%
Short circuit any two pins 20%
