Power Supplies

±12 V @ 200 mA
5 V @ 250 mA

TTL/CMOS Operation

Selectable output voltage of clock, pulser, & logic switches. 
Input voltage thresholds of seven segment displays, logic indicators and Vcc tie-points between 5 V, TTL and 12 volts, CMOS



Fixed at three levels: 1 Hz, 1 kHz, 100 kHz


Two fully-debounced pushbuttons with true logic and complementary outputs. 
Logic "1" output current 2 mA @ 4 V min (5 V/TTL)
Logic "1" output current 4 mA @ 11 V min (12 V/CMOS)
Logic "0" output current 2 mA @ 0.1 V max (5 V/TTL)
Logic "0" output current 5 mA @ 0.1 V max (12 V/CMOS)

Logic Switches

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

Logic Indicators

Eight LEDs buffered by two four-bit latches with separate enables.
Input impedance, all inputs: 100 kΩ


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 kΩ


All functions are permanently tied to three solderless tie-point connectors. 
Each tie-point has two 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.


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


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

Weight1 lb. 9 oz

Overall Dimensions : 2.6 H x 7.5 W x 10 D (inches)
