RC Networks

Resistor Networks

Individual Resistors, common connection
Common usage; tie pin 16 to Vcc, and use each resistor as a pull-up. Note the decoupling capacitor, so each line pulled high gets decoulped.

Pull-up Network IC, Common Resistor Network
Common Resistor Network

Resistor Network, parallel connection [Thevenin]
Common usage; bus termination.

Resistor Termination Network, parallel
Resistor Termination Network

Normally pins 1 and 10 to 16 are taken to Vcc and pin 8 and 9 is taken to ground. The remaining pins 2 to 7 are connected to the interface bus data lines.

Refer to the page on Resistor Networks for common values used as resistor terminations.

In both of the network packages a decoupling capacitor [internal to the package] is placed between pin 16 and pin 8. A normal 16-pin DIP IC receives power on pin 16 and is grounded on pin 8, so common layout would place a capacitor between these two pins. The second package also has pins 1 and 9 open [unused] which could also be used as decoupling pins.
