How do I drive the input side?
The input side is an infrared LED, so drive it through a series current-limiting resistor sized for the forward current in the datasheet (50 mA maximum as listed).
Does the output need a pull-up or load resistor?
Yes. The phototransistor output needs a collector resistor to produce a logic-level signal. Choose its value based on the speed and current you need, following the datasheet.
