General Information
Bussed Resistor networks are typically used in DC pull-up
and pull-down applications where system data or control lines
must be tied to a fixed potential. Fabricated with a Tantalum
Nitride and Nickel Chromium on Silicon process, these
resistors feature excellent stability, TCR and tracking
performance. Bussed Resistor Networks are available in a
range of miniature package types conforming to JEDEC
standards.
