Note:

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.

DEFINITIONS

CL = Load capacitance includes jig and probe capacitance;

see AC CHARACTERISTICS for value.

NOTES:

1. All input pulses are supplied by generators having the following

characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.

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

measurement.
