7 Parameter Measurement Information

Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, Z_O = 50 Ω, t_t < 6 ns.

For clock inputs, f_max is measured when the input duty cycle is 50%.

The outputs are measured one at a time with one input transition per measurement.

(1) C_L includes probe and test-fixture capacitance.
