Global Specialties PB-501 Data Sheet

Ideal for digital logic circuit design and

experimentation
Compact design for easy storage
Includes built-in Clock, Pulsers and Logic Switches
Premium breadboarding area with 8 power rails
3-year warranty on all parts and workmanship.

The PB-501 Logic Design Trainer is a low cost
portable trainer, which is capable of
satisfying many requirements arising in the
design and study of digital logic circuitry. The
PB-501 can be powered-up via batteries,
optional wall-mount power adapter, or by an
external 5V power supply. The PB-501 can be
utilized for the design and study of gates,
counters, multiplexers and can even interface
directly to a microprocessor. The PB-501 is
housed in a tough molded plastic carrying
case with an integral hinged cover which
stacks conveniently for storage. Utilizing the
PB-501, students will learn valuable hands-on
breadboarding techniques and build a solid
foundation in digital logic circuit
experimentation, construction and analysis.

Global Specialties trainers provide the most
complete platform required to enable
engineers and technicians to train for careers
in the rapidly growing field of electronics
technology.

Use the PB-501 to
construct a wide variety
of experiments, including
but not limited to:

Logic Gates & Boolean
Algebra
Combinational Logic
Circuits
Flip-Flops
Counters & Register
Circuits
Integrated Logic Circuits
TTL Logic
MOSFETS
CMOS
Interfacing CMOS & TTL
Medium Scale Integration
Decoders
Encoders
