7 / 9 page  Applications Information (Continued) 2. Terminated Input. If the driver is disconnected (cable unplugged), or if the driver is in a TRI-STATE or power- off condition, the receiver output will again be in a HIGH state, even with the end of cable 100 Ω termination re- sistor across the input pins. The unplugged cable can become a floating antenna which can pick up noise. If the cable picks up more than 10mV of differential noise, the receiver may see the noise as a valid signal and switch. To insure that any noise is seen as common- mode and not differential, a balanced interconnect should be used. Twisted pair cable will offer better bal- ance than flat ribbon cable. 3. Shorted Inputs. If a fault condition occurs that shorts the receiver inputs together, thus resulting in a 0V differ- ential input voltage, the receiver output will remain in a HIGH state. Shorted input fail-safe is not supported across the common-mode range of the device (GND to 2.4V). It is only supported with inputs shorted and no external common-mode voltage applied. External lower value pull up and pull down resistors (for a stronger bias) may be used to boost fail-safe in the presence of higher noise levels. The pull up and pull down resistors should be in the 5k Ω to 15kΩ range to minimize loading and waveform distortion to the driver. The common-mode bias point should be set to approximately 1.2V (less than 1.75V) to be compatible with the internal circuitry.
