Vishay Thin Film
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.

SCHEMATICS
RESISTORS WITH ONE PIN COMMON
The 01 circuit provides nominally equal resistors connected
between a common pin and a discrete PC board pin.
Commonly used in the following applications:
•MOS/ROM pull-up/-down
•Open collector pull-up
•"Wired OR" pull-up
•Power driven pull-up
•TTL input pull-down
•Digital pulse squaring
•TTL unused gate pull-up
•High speed parallels pull-up
Broad selection of standard values available
ISOLATED RESISTORS
The 03 circuit provides nominally equal resistors isolated
from all others and wired directly across.
Commonly used in the following applications:
•"Wired OR" pull-up
•Power driven pull-up
•Powergate pull-up
•Line termination
•Long-line impedance
balancing
•LED current limiting
•ECL output pull-down
•TTL input pull-down
Broad selection of standard values available
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.
Standard values are:
VSSR1605:
R1 = 220 Ω, R2 = 330 Ω
R1 = 330 Ω, R2 = 470 Ω
VSSR2005:
R1 = 220 Ω, R2 = 330 Ω
R1 = 220 Ω, R2 = 1.8 kΩ
R1 = 1.5 kΩ, R2 = 3.3 kΩ
DIFFERENTIAL TERMINATOR
The 47 schematic consists of series resistor sections
connected between VCC and ground. Each contains 3
resistors of 2 different resistance values.
Standard values are:
VSSR20 and VTSR20:
R1 = 270 Ω, R2 = 120 ΩVSSR16 and VTSR16:
R1 = 330 Ω, R2 = 150 Ω
R1 = 330 Ω, R2 = 220 Ω
