3 Failure Mode Distribution (FMD)

The failure mode distribution estimation for SN74LVC3G07-Q1 in Table 3-1comes 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 (%)
Output stuck at fault	20%
Output open (HIZ)	20%
Output functional – out of specification timing or voltage	40%
