The differential receivers of the THVD24x9 family are failsafe to invalid bus states caused by the following:

• Open bus conditions, such as a disconnected connector
• Shorted bus conditions, such as cable damage shorting the twisted-pair together
• Idle bus conditions that occur when no driver on the bus is actively driving

In any of these cases, the receiver outputs a fail-safe logic high state if the input amplitude stays for longer than t_D(OFS) at less than |V_{TH_FSH}|.
