PB-501 Logic Design Trainer
The low cost PB-501 Logic Trainer permits students of digital electronics to make efficient use of valuable laboratory time. Circuits such as clocks, switches and lights are permanent parts of the PB- 501 and need not be repeatedly constructed. Students build only those circuits which directly pertain to a particular experiment.
Everything required to design and experiment with logic circuitry is included in the PB-501. Power is supplied by either four 1.5V batteries or an optional AC adapter. The PB-501 is housed in a tough molded plastic carrying case with an integral hinged cover which stacks conveniently for storage.
1 KHz user variable with external capacitor Logic “1” output current 100 mA max Logic “0” output current 100mA max
Pulsers
Logic “1” output current 400µAmps Logic “0” output current 16mA max
Logic Switches/Input Ports
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 @ 5VDC Logic “0” input current none required.
Logic Indicators
Dual function: 8 LEDs driven by two 4-bit latches with separate enables
Output Ports
Logic “1” input current 50µA @ 5VDC Logic “0” input current none required
Connectors
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.
Breadboarding
One UBS-100 solderless breadboarding socket is permanently attached to the unit. The UBS-100 can accomodate 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
