Vishay Foil Resistors  
Bulk Metal® Foil Technology  
16 Pin Transistor Outline Hermetic Resistor Network  
The 16 Pin TO-8 package is suitable for ladder networks up to  
12 bits and other more complicated networks. It is also a good  
choice when power dissipation is a consideration. This network  
can contain up to 49 V5X5 resistor chips.
