circuits
Vishay Thin Film resistor networks are designed to be used
in either analog or digital circuits. The use of thin film
resistive elements within the network allows you to achieve
an infinite number of very low noise and high stability circuits
for industrial, medical and scientific instrumentation. Vishay
Thin Film resistor networks are packaged in molded plastic
packages with sizes that are recognized throughout the
world. The rugged packaging offers superior environmental
protection and consistent dimensions for ease of placement
with automatic SMT equipment. Vishay Thin Film stocks
many designs and values for off-the-shelf convenience.
With Vishay Thin Film you can depend on quality products
delivered on time with service backing the product.
• Compliant to RoHS directive 2002/95/EC

Resistance Range:
10 Ω to 47 kΩ
• MOS/ROM pull-up/-down • TTL input pull-down
• Open collector pull-up
• "Wired OR" pull-up
• Power driven pull-up
• Digital pulse squaring
• TTL unused gate pull-up
• High speed parallels pull-up

03 SCHEMATIC
ISOLATED RESISTORS
The 03 circuit provides nominally equal resistors isolated
from all others and wired directly across.
Commonly used in the following applications:
Resistance Range:
10 Ω to 47 kΩ
• "Wired OR" pull-up
• Power driven pull-up
• Powergate pull-up
• Line termination
• Long-line impedance

05 SCHEMATIC
DUAL-LINE TERMINATOR; PULSE SQUARING
The 05 circuit contains pairs of resistors connected between
ground and a common line. The junctions of these resistor
pairs are connected to the input leads. The 05 circuits are
designed for dual-line termination and pulse squaring.
