4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the TMUX1308-Q1 and TMUX1309-Q1 (TSSOP, SOT-23-THIN, and WQFN packages). The failure modes covered in this document include the following typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-2 and Table 4-10)
• Pin open-circuited (see Table 4-3 and Table 4-11)
• Pin short-circuited to an adjacent pin (see Table 4-4 and Table 4-12)
• Pin short-circuited to VDD (see Table 4-5 and Table 4-13)

Table 4-2 through Table 4-4 also indicate how these pin conditions can affect the device per the failure effects classification in Table 4-1.
