Overview

PB-502® - Advanced Logic Design Trainer

Specifications

Power Supplies:
+12 volts + 5% 200mA max.; -12 volts +5% 200mA max., +5 volts +5% 250mA max.

TTL/CMOS Operation:
Selectable output voltage of clock, pulser, logic switches. Input voltage thresholds of seven segment displays, logic indicators and Vcc tie point between 5 volts, TTL: and 12 volts, CMOS.

Clock:
1 Hz +20%; 1 kHz +20%. 100 kHz +20%. Also user variable with external capacitor. Logic “1” output current 2mA @ 4.0V min. (5 V/TTL); 4mA @ 11.0 V min. (12 V/CMOS). Logic “0” output current 2mA @ 0.1V max. (5 V/TTL); 5 mA@0.1V max (12 V/CMOS)

Pulsers:
Two fully debounced pushbuttons with true logic and complementary outputs.
Logic “1” output current 2 mA @ 2.5 V min. (5 V/TTL); 2 mA @
11.0 V min. (12 V/CMOS)
Logic “0” output current 2 mA @ 0.4V max. (5 V/TTL); 5 mA @ 0.4V
max (12 V/CMOS)

Logic Switches:
8 SPDT switches select output of Vcc or ground. Output current, all cases: 200 mA max

Logic Indicators:
8 LEDs buffered by two four-bit latches with separate enables. Input impedance, all inputs: 100 k ohms

 

Seven-Segment Displays:
Two BCD-input seven-segment displays with separate Display Enable (DE), Latch Enable (LE), and Lamp Test (LT) inputs. Input impedance, all inputs: 100 K ohms.

Connectors:
All functions are permanently tied to three solderless tie point connectors. Each tie point has 2 solderless connection points. Ground, +5 volts, Vcc, and clock out have four connection points each. All tie point functions are labeled on the front panel.

BNCs:
Two BNC connectors with the shells tied to ground and the pins connected to adjacent single tie points.

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 five tie points per pin plus eight power rails with 25 tie points each.

Dimensions: 2.6”H x 7.5”W x 10” D

Weight: PB-502: 1 lb. 9 oz.
PB-502 with charger: 4 lb.
Includes AC Power Adapter, model 900CA-1

Model Number 104-0502
