Note 3: A differential terminating resistor is required for proper function of open-circuit fault detection (see Applications Information).

Note 4: See Applications Information for a discussion of the receiver common-mode voltage range and the operating conditions for

fault indication.

Note 5: Applies to the individual channel immediate-fault outputs (ALARM_) and the general delayed-fault output (ALARMD) when

there is no external capacitor at DELAY.
