12-stage binary ripple counter
a. Input waveforms
b. Test circuit
Test data is given in Table 9.
Definitions test circuit:
DUT = Device Under Test;
CL = load capacitance, including the jig and probe capacitance;
RL = load resistance, which should be equal to the output impedance of the pulse generator.
