DS10CP152: Input pins when unused

Simon

The receiver inputs of the DS90CP152 do not have internal fail-safe biasing. For point-to-point and multidrop applications with a single source, fail-safe biasing may not be required. When the driver is off, the link is inactive. If fail-safe biasing is required, this can be accomplished with external high value resistors. The IN+ should be pull to Vcc with 10kΩ and the IN− should be pull to Gnd with 10kΩ. This provides a slight positive differential bias, and sets a known HIGH state on the link with a minimum amount of distortion.
