I normally understand a resistor to bridge two points in a circuit. How can resistor networks possibly do this when each resistor only has a single pin? Or if one end is shared if you will (such that all of them might be tied to ground or Vcc) how does that work if you say wanted 8 current limiting resistors between a row of LEDs and the data pins on some kind of IC?
If you check the data sheet available on the website you linked to you will find circuit diagrams of the types of resistor networks available. It shows 3 variations but in my (limited) experience the isolated type (each resistor has a pair of leads) and the bussed type (each resistor is tied to a common bus) are the most common. It sounds like you would be looking for the bussed variety.
