Feature Description (continued)
External lower value pullup and pulldown resistors (for a stronger bias) may be used to boost fail-safe in the
presence of higher noise levels. The pullup and pulldown resistors should be in the 5-kΩ to 15-kΩ range to
minimize loading and waveform distortion to the driver. The common-mode bias point should be set to
approximately 1.2 V (less than 1.75 V) to be compatible with the internal circuitry.
