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.

NOTE:
1. These networks utilize Vishay Bulk Metal
®
Foil resistor
chips V5X5 and V15X5 or VTF15X5 Thin Film chips.
2. The V5X5 and V15X5 chips have maximum resistance
values of 10K and 33K respectively in Bulk Metal
®
Foil
and 500K in VTF15X5 Thin Film chips.
3. The V5X5 and V15X5 chip(s) can be intermixed in a
package.
