About Global Specialties PB-501 Portable Logic Design

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. 4 "C" batteries (not included). Optional 6 VDC battery adapter,300mA, unregulated Model 1200CA-1. 1 KHz user variable with external capacitor Logic "1" output current 100 mA maxLogic "0" output current 100mA max. Logic "1" output current 400µAmpsLogic "0" output current 16mA max. Dual Function: 8 switches buffered by two 4 bit tri-state buffers with separate enables Logic "1" output current 2.6 mA max, Logic "0" output current 24 mA max Enables Logic "1" input current 400mA at 5VDC Logic "0" input current none required. Dual function: 8 LEDs driven by two 4-bit latches with separate enables. Logic "1" input current 50micoampere at 5VDC Logic "0" input current none required. All functions are permanently connected to a solderless tie point connector. Each tie point has 5 solderless connection points. Power and ground have 15 connection points each. All tie points are labeled. One UBS-100 solderless breadboarding socket is permanently attached to the unit. The UBS-100 can accommodate up to eight 14 pin DIP ICs with 4 tie points per pin plus eight power rails with 25 tie points each, total 840 tie points. Measures 7-1/2" width by 2-35/64" height by 10" depth.
