NOTES: A. CL includes probe and jig capacitance.

B. All input pulses are supplied by generators having the following characteristics: PRR â¤ 1 MHz, ZO â 50 â¦, tr â¤ 15 ns, tf â¤ 6 ns.

C. When measuring propagation delay times and skew, switches S1 and S2 are open.

D. Each enable is tested separately.

E. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.

Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.
