The PB-502 Advanced Logic Design Trainer is a portable robust instrument capable of satisfying many requirements arising in the design and study of digital logic circuitry. The PB-502's selectable operating voltage further aids its versatility by allowing the trainer to be used in either TTL or CMOS operating mode, The trainer contains three integral power supplies and input/output devices that simplify the construction of a wide range of circuits. Typical circuits that can be built on the PB-502 include, operational amplifiers, comparators, A to D converters, gates and counters. The PB-502 can also interface directly to a microprocessor. The PB-502 is housed in a tough, molded plastic carrying cases with an integral hinged cover which stacks neatly for storage. Typical experiments and circuits that can be design utilizing the PB-502 include, but are not limited to the following. Read Less...
