Note 1: VCM is the common-mode input voltage. VID is the differential input voltage.
Note 2: VIN is the input voltage at pins A, A, B, B, Z, Z.
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.
Note 6: Equivalent pulse test: 1.3V / (tDFLH - tDFHL) ≥ SRD.
Note 7: Equivalent pulse test: 0.62V / (tDFLH - tDFHL) ≥ SRD.
